#22416 [Com]: failed to create stream: Too many open files in Unknown on line 0
ID: 22416 Comment by: mytto at openxtrem dot com Reported By: jhalla at legion dot org Status: Bogus Bug Type: iPlanet related Operating System: Solaris 8 PHP Version: 4.3.5 Assigned To: wez New Comment: definitely sure, i checked it out twice :) Unfortunately I don't have root access to my webspace but only FTP and Plesk admin... Shall I request these modifications to my provider? Can I check those values from a web browser anyhow? Thanks for you help Previous Comments: [2004-09-06 21:59:30] [EMAIL PROTECTED] Are you sure that you are using 4.3.5? If yes, then you have really to few file handles and this problem have nothing to do with PHP. SunONE recommends for the webserver to raise the hard limit of open files (must be done by root in /etc/system): set rlim_fd_max=8192 set rlim_fd_cur=1024 [2004-09-06 21:44:41] mytto at openxtrem dot com Unfortunately ih happens rather randomly on many websites I host, which are themselves instances of opensource solutions like Mambo, TikiWiki or dotProject. It's often a fopen() fonction call that raise a 'failed to create/open stream: Too many open files'. The trick is that when I refresh several times, it happens work back again... I'm quite puzzled :/ [2004-09-06 13:56:39] [EMAIL PROTECTED] In which context does that happen? Any function call? The Zend engine itsself has no further limitations. Only 3rd party modules can run into this limitation if they use stdio which is limited in Solaris 32bit (even 3rd party libs that are used by a PHP extension). Libs/Extensions that have problems (as I know): * sybase/sybase_ct (in the libs of Sybase, not PHP) -> use freetds here * imap extension (no further testing), depends on the imap library used * older MySQL libs, use newest one, not the bundled one In PHP itsself one of this are currently the mail() function because it uses stdio pipes to send data to sendmail. [2004-09-06 13:42:47] mytto at openxtrem dot com Though I'm running PHP 4.3.5, I encounter the same problem. Do you have another solution? [2003-10-11 12:02:11] [EMAIL PROTECTED] Use the newest version of PHP (4.3.3 or greater). There this limit is removed. Your comment to 64bit is not acceptable for iPlanet users because iPlanet is a 32 bit webserver which cannot run modules compiled in 64 bit.

ID: 22416 Comment by: jmorris at sunflower dot com Reported By: jhalla at legion dot org Status: Bogus Bug Type: iPlanet related Operating System: Solaris 8 PHP Version: 4.3.0 Assigned To: wez New Comment: While the 32-bit libc stdio is limited to 256, the 64-bit libc stdio is not. Try compiling in 64-bit mode (gcc -m64). Test programs indicate that the limit is removed in 64-bit programs, I have not yet built apache and php in 64-bit mode. http://access1.sun.com/technotes/01406.html Previous Comments: [2003-04-09 17:28:00] [EMAIL PROTECTED] Let me reiterate the cause of the problem: **Solaris libc stdio is broken** This is not really a bug in PHP. The only workaround for PHP < 5 is to link against an alternative stdio library, such as the AT&T sfio, although some people are reporting problems compiling that on their Solaris systems. PHP 5 will (and does) avoid stdio like the plague, so it does not fall victim to this Solaris deficiency. The changes required to make PHP 4.3.x do the same are too big to introduce into the stable branch (they require some potentially unstable changes to the Zend Engine). This report is marked as bogus as it is a duplicate of another report that we found more useful for bug-fixing purposes. [2003-04-09 16:51:51] [EMAIL PROTECTED] Please do not submit the same bug more than once. An existing bug report already describes this very problem. Even if you feel that your issue is somewhat different, the resolution is likely to be the same. Because of this, we hope you add your comments to the existing bug instead. Thank you for your interest in PHP. , [2003-04-09 15:11:36] jhalla at legion dot org "No feedback was provided. The bug is being suspended because we assume that you are no longer experiencing the problem. If this is not the case and you are able to provide the information that was requested earlier, please do so and change the status of the bug back to "Open". Thank you." Sniper, the bug isn't resolved... PHP 4.3x still does not run on iPlanet/Solaris. [2003-04-09 15:09:58] fillmore at nrcan dot gcc dot a We have been having these problems also. I just installed php-4.3.2RC1.tar.gz to see if it helps, and the site started failing again within a half hour. I doubt that it's an open file limit in libc, because the site had only 14 hits on .php URLs before it started failing. Also, only two scripts were called, and they don't open any files. Here's the code in the most complicated of the two scripts: ' .substr($val,strrpos($val,"*")+1).' '; } ?> - Bob Fillmore [2003-03-13 14:59:22] [EMAIL PROTECTED] The issue is that the (brain-dead) solaris libc has a hard limit of 256 FILE*s.
