This bug has been fixed in CVS. In case this was a PHP problem, snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. In case this was a documentation problem, the fix will show up soon at http://www.php.net/manual/.

Previous Comments: ------------------------------------------------------------------------ [2003-12-10 09:19:56] [EMAIL PROTECTED] it seems to me, this bug appears due to the fact, that current implementation of ext/oci8 doesn't use OCI_THREADED flag with OCIInitialize(); Maxim tells about it here: http://www.zend.com/lists/php-dev/200301/msg00213.html OCI docs about OCI's thread safety are here: http://docs.linux.cz/Oracle8/server/a58234/new_adva.htm#427495 I think, I can add this feature shortly. ------------------------------------------------------------------------ [2003-12-10 05:56:13] k_becker at kat dot de I tried the "MaxThreadsPerChild=1" from Bug#19517. No crashes, but Apache "... ran out of threads". Then set MaxRequestsPerChild 100000, ThreadsPerChild 100 and tried using the explicit Oracle address string from TNSnames.ora. This seems to work. Then tried php4-win32-STABLE-latest.zip of 2003-dec-10: Same result. I now have: Apache/1.3.28 (Win32) PHP/4.3.5-dev, OCI8 Revision: 1.183.2.7 on Windows 2000 adv. server build 2195 with MaxRequestsPerChild 100000, ThreadsPerChild 100. Temporary solution seems to be using the TNS address string in OCILogon("user", "pass", "(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=127.0.0.1)(PORT=1521)))(CONNECT_DATA=(SID=xxx))") So, problem seems to be in the Oracle/Oci8 name resolving in concurrent OCILogon()'s from multiple Apache/PHP-threads. ------------------------------------------------------------------------ [2003-12-09 04:38:27] k_becker at kat dot de Description: ------------ Platform: 4-CPU machine, Apache 2.0.39..48, PHP 4.3.x, Win 2000 Adv. server engl., OCI8, Oracle 8.1.7EE When issuing multiple Oracle-requests at once, the Apache client thread dies with protection fault (C0000005) without any further message from PHP, Oracle or Apache. Same code runs okay on one-CPU machine with same platform. Changing Apache to 1.3.28 helped. Could be a problem within the PHP for Apache2 parallelization on more than one CPU. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26558&edit=1
