#18933 [Com]: MSSQL issues under stress
ID: 18933 Comment by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Open Bug Type: MSSQL related Operating System: win2k PHP Version: 4.2.2 New Comment: Looks like two separate bugs. #1 - this would be a problem with your MS SQL server settings. Not a PHP issue. #2, #3, #4 - are you running as an ISAPI or CGI? There are issues with PHP ISAPI under stress. Previous Comments: [2002-08-15 20:43:32] [EMAIL PROTECTED] The MSSQL extension seems to have a few issues under heavy stress. Running a similar test with a mysql server produces no errors: Running the above test script produces the following error log entries: 1. MS SQL: Unable to connect to server: 127.0.0.1 --> mysql doesn't fail taking new connections, but that error could be a server config setting. 2. Corrupt Log file Entries e.g. : ndex.php on line 3 2 ine 8 tdocs\php\index.php on line 8 3. Failure connecting to server "null": MS SQL: Unable to connect to server: (null) (should be 127.0.0.1) 4. Attempting to connect as a null user: MS SQL message: Login failed for user '(null)'. (should be "1") Paul -- Edit this bug report at http://bugs.php.net/?id=18933&edit=1

ID: 17563 Comment by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Open Bug Type: MSSQL related Operating System: WIN2K PHP Version: 4.2.1 New Comment: Can you please be very specific about your table and column names. The ODBC driver doesn't handle odd names very well. There's a big difference between: SELECT * FROM froo SELECT * FROM [FR oO] Previous Comments: [2002-08-25 23:54:30] [EMAIL PROTECTED] Yes, try that first, after recreate the data field, I have no problem afterwards. You can use the mssql.dll if you want~ I use that in all time, I don't like ODBC, [2002-08-25 00:51:28] [EMAIL PROTECTED] Hi I Have this problem Too I use an Odbc conennection on Win2000 prof and IIS ver 5 I try to fetch some data from my database by this lines : $query="Select username,name,family,Sex,pic,pic_type ,about from [users]"; ... ... $username = odbc_result($result, 1); $name = odbc_result($result, 2); this page is work probebly at first time but after some refreshing I recive "PHP has encountered an Access Violation at X" only at this page and other .php page is work probebly; I install PHP on my computer in ISAPI mode in my users table "Pic_type" and "about" allow null I rename these fieldes but not effect . you say I remove this field's and add them again ? is it effective? I try it but not sure thank's [2002-06-08 20:28:34] [EMAIL PROTECTED] Server Version: MSSQL Server 2000 Operating System: WIN2K Server Database Details: The error field is smallmoney, allow null. Error Solution: I've tried rename it with other field which is also 'smallmoney' and 'allow null', but problem does not solve this way. The only way to solve this problem is to remove that field and create another new field again. Notice: Notice that the field works fine inside the MSSQL server's 'Query Analyzer', no error occur inside MSSQL server itself, but it produce error with the PHP engine. How does the bug act like: This error might not hang the whole php engine in first few times you recieve the message "PHP has encountered an Access Violation at ", but it will eventually hang when you load that page few more times. [2002-06-08 05:05:19] [EMAIL PROTECTED] That's a start (and probably not a duplicte). But we need more information. What vrsion of MSSQL ? And type was this field of ? Can you reproduce this by creating a second field exactly as the first which crashes, which crashes too ? Please be as detailed as possible about the database setup and the field in general (so someone with the appropriate environment can rebuild this scenery), thx. [2002-06-08 04:54:26] [EMAIL PROTECTED] GUYS!! Found it, as I said, there is one field have error, I remove that field and add another field that is exactly the same datatype and everything and the problem solved. Try it out.

#16411 [Com]: CGI application misbehaved by not returning a complete set of
ID: 16411
Comment by: [EMAIL PROTECTED]
Reported By: [EMAIL PROTECTED]
Status: Open
Bug Type: MSSQL related
Operating System: Windows 2000
PHP Version: 4.1.2
New Comment:
What are you doing with your database connections? Are they persistant
(mssql_pconnect) or transient (mssql_connect)? Do you close your
connections explicitly (mssql_close) before the end of your script?
vielina, your connections will be closed each time as you are running
under the CGI.

I have this problem too.
[2002-06-20 15:19:45] [EMAIL PROTECTED]
Same problem, slightly different case...
win2000 running php.exe 4.2.1 (and mssql 2000)
seems to happen mostly during redrects like...
header("Method: GET");
header("Status: 302 Moved");
header("Location: ". $ABSOLUTE_URL);
some claim they solved this problem by applying the workaround by
microsoft (Q160422).
others say they have fixed this by blanking out the doc_root in
php.ini
I still have this problem
[2002-06-02 22:14:18] [EMAIL PROTECTED]
I did that but it still did not work. I further tested another way: I
left every thing as it was, except that I did not open an MSSQL
connection. The script worked pretty well. When I changed it back, the
same type of bug happened. When looking at phpinfo, even with the
latest php version (4.2.1) I saw that in the MSSQL support section, the
MSSQL library version was 7.0. Is this a potential source of that bug?

Please try it again with a right header like Location:
http://www.domain.tld/some.php. Location header needs a complete
absolute URI.

[2002-04-03 09:46:44] [EMAIL PROTECTED]
I have the same set of php scripts, php 4.0.6 CGI running on:
1-Windows NT 4.0 with IIS4, MySQL, MS-SQL 7; this works fine;
2-Windows 2000 server with IIS5, MySQL, MS-SQL 7; this works fine;
3-Windows 2000 advanced server with IIS5, MySQL, MS-SQL 7; this works
fine;
4-Windows 2000 advanced server with IIS5, MySQL, MS-SQL 2000; this
still
works except that a curious error occurs:
Im using a lot of Header ("location: some.php") for redirections. In
this
particular installation, right after the call of header function, the
browser
still gets the right URI, but then it issues the following error (a
copy
again here):
CGI ERROR
CGI application misbehaved by not returning a complete set of
headers.The headers that it did return are:
The funny thing was that if I refresh the page then it works just
fine.
When I look back at the 4 installations, the only difference was the
installation 4: MS-SQL 2000.
I later made another test: from the installation 3, I made an upgrade
of MS SQL from 7.0 to 2000. The same problem happened.
I have tested with php 4.1.2 and 4.0.6. I had the same symptoms with
both versions
Is there anything in php_mssql that does the job with MS-SQL 2000 but
has some sort of side-effect that causes the above strange bug?
Would any one spend time looking into the code? It
would help us a lot.
Thank you very much!

ID: 15333 Updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Critical Bug Type: IIS related Operating System: Windows 2000 Pro PHP Version: 4.2.0 RC2 New Comment: There is a tool called "tkill" / kill / tlist that will let you terminate processes. Get the PID from tlist or Task Manager and then run kill with the PID for the argument. inetinfo.exe will be running under a different user that Administrator does not have the power to kill the processes of, so using Task Manager to kill inetinfo.exe is a waste of time. Previous Comments: [2002-04-21 06:32:35] [EMAIL PROTECTED] I tried setting the app protection to 'Low (IIS Process)' and still get the error. And I tried killing inetinfo.exe and running the net stop commands from the command line, but Windows won't kill the process. This issue has turned out to be the biggest reason my I haven't embraced PHP yet -- because I hate rebooting my machine all of the time. I would love to hear of a workaround that works, and better yet, see a published fix. Any more ideas out there? [2002-04-17 15:19:04] [EMAIL PROTECTED] I am getting this error with 4.2.0 RC2.

You can restart IIS without rebooting, you've got to perform the following: kill the inetinfo.exe process using the task manager run from command line: net stop w3svc net stop iisadmin net start iisadmin net start w3svc Marking this bug critical because it should be fixed before 4.2.0 release.

Bug #16325: Memory leak causes DLLHOST to become large
From: [EMAIL PROTECTED] Operating system: Windows 2000 Server PHP version: 4.1.2 PHP Bug Type: IIS related Bug description: Memory leak causes DLLHOST to become large The setup: IIS5 has an ISAPI application mapping to php4isapi.dll Steps to reproduce: - Start IIS - Generate heavy load (~40+ hits / second) - Watch DLLHOST in the Task Manager. It takes more and more memory (40 - 45MB) - PHP error log begins reporting spurious errors (the page has no errors, but under heavy load it starts complaining about duplicate function definitions) Bug: #13324 - IIS stops serving PHP files but still serves static content DLLHOST disappears from the task list at this point. Other times it may begin taking 100% CPU and need to be terminated by hand. Killing DLLHOST usually causes it to be restarted and requests continue being served.

ID: 13324 Updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Open Bug Type: IIS related Operating System: Windows 2000 SP2 PHP Version: 4.0.6 New Comment: I've reproduced this without Zend Optimizer. Under heavy load (45 requests / second) I received a number of errors about being unable to redeclare functions. Under low load there were no complaints. PHP 4.2.0 / IIS 5 / Windows 2000 Previous Comments: [2002-02-19 08:55:18] [EMAIL PROTECTED] Are you using Zendencoder? I have the same problem on a machine running Zendoptimizer with some pages that were Zendencoded. The server crashed every 20-30 request or so. I took off the pages Zendencoded and its working fine now... Seems that the problem stands there...It is not the Zendoptimizer, cause it is still in the php.ini and it works fine. [2001-09-15 20:50:27] [EMAIL PROTECTED] After further investigation, this seems to be a hint to a higher IIS threading problem rather than a problem specific to Zend Optimizer. If I create a php page with the function getmicrotime() in it and then call this page from 5 different browser windows at about the same time, I receive the following error: Fatal error: Cannot redeclare getmicrotime() in C:\Websites\mysqlconnect.php on line 2 I've also confirmed that variables declared within the realm of the script are also available to other browser sessions. For example, creating a random number in a script and then executing a time consuming for-loop will result in more than one window ending up with the same random number. [2001-09-15 20:12:40] [EMAIL PROTECTED] As a follow-up, with ZendOptimizer.dll uncommented in the php.ini file: Each IIS restart and request to the php webpage will result in a new instance DLLHOST.exe being created in the Windows Task Manager. Older DLLHost.exe instances are not released with IIS Reset. [2001-09-15 19:45:40] [EMAIL PROTECTED] This is a fresh install of PHP 4.0.6 on a new install of Windows 2000 server with service pack 2. Zend Optimizer is installed and the site is in Medium (pooled) mode. I am using the php4isapi.dll. There are no other programs or services installed on this machine. The code executing is a single pconnect request to a MYSQL server and then a mysql_close() request. The code is not Zend optimized. If I enable ZendOptimizer.dll in the php.ini and execute the code, it operates fine. But if I reset the IIS service, the server returns the following 2 errors randomly: 1) -2147417842 (0x8001010e) 2) Invalid access to memory location. If I comment out the ZendOptimizer.dll in the PHP.ini file and then restart the web service, operation resumes as normal. I believe the IIS Web Service is not releasing the ZendOptimizer.dll from memory and then trying to reload it when PHP is called. This may be a hint to all the access violations every one is getting. -- Edit this bug report at http://bugs.php.net/?id=13324&edit=1
