From: barry at hpfm dot com dot au Operating system: Redhat 9.0 PHP version: 4.3.5 PHP Bug Type: Session related Bug description: Mssql.c runtime error
Description: ------------ I am developing an application that runs php on Rh9.0,Apache1.3 that accesses data residing on a Windows SBS server running SQLSERVER. I am getting huge apache error_log files (see attached sample) because of a memory leak in msssql.c. The application runs quite slowly and really hammers the apache server. The application is using PEAR DB, DBO. Occassionally the $dbo->find() will not return anything at all. Reproduce code: --------------- <?php require_once "config.php"; require_once "DataObjects/Person.php"; require_once "DataObjects/Members.php"; $person = new DataObject_Person; $member = new DataObject_Members; echo "Starting DB Tests: find all CPl members<br>"; $member->debugLevel(0); echo "Issue find request<br>"; $transfers=$member->find(); echo $transfers." CPL folk to translate<br>"; while ( ( $member->fetch() ) ) { echo "<pre>"; var_dump($member->toArray()); echo "</pre>"; } ?> Actual result: -------------- --------------------------------------- [Tue May 25 08:47:49 2004] Script: '/www/sites/slsa/SLSA_Members/include/DBTes ts01.php' --------------------------------------- /downloads/php4.3/php4.3.5/php-4.3.5/ext/mssql/php_mssql.c(191) : Block 0x083839 00 status: /downloads/php4.3/php4.3.5/php-4.3.5/Zend/zend_variables.c(44) : Actual location (location was relayed) Beginning: OK (allocated on /downloads/php4.3/php4.3.5/php-4.3.5/ext/mssql/ php_mssql.c:847, 19 bytes) End: Overflown (magic=0x2A8FCC00 instead of 0x2A8FCC84) 1 byte(s) overflown --------------------------------------- -- Edit bug report at http://bugs.php.net/?id=28512&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=28512&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=28512&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=28512&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=28512&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=28512&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=28512&r=needscript Try newer version: http://bugs.php.net/fix.php?id=28512&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=28512&r=support Expected behavior: http://bugs.php.net/fix.php?id=28512&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=28512&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=28512&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=28512&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=28512&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=28512&r=dst IIS Stability: http://bugs.php.net/fix.php?id=28512&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=28512&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=28512&r=float
