ID: 28603 User updated by: uncle at fedor dot com Reported By: uncle at fedor dot com -Status: No Feedback +Status: Open Bug Type: Apache2 related Operating System: SuSE Linux 8.2 -PHP Version: 4.3.7RC1 +PHP Version: 4.3.7 New Comment:
I tried to generate a backtrace according to a standard procedure, but as soon as httpd2-worker is started with the -X switch, it *does not* die when 'apache2ctl graceful' command is issued. That tells me the following: when Apache is run with the -X switch only 1 thread is started. Normally there is more than one thread (it is a -worker). Therefore one could assume the segmentation fault happens because of multiple threads and OCI8 module incompatibility. httpd2-prefork also works fine with OCI8 module by the way. The above poses a few questions: a) Is OCI8 module not thread-safe? b) Is it a problem of Oracle 9.0.2 Client libraries? c) Can the problem be traced futher? d) Shall I give up and use the prefork mpm? Thanks!

To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. ------------------------------------------------------------------------ [2004-06-01 14:57:14] uncle at fedor dot com Description: ------------ It looks like a similar bug (#27810) was fixed when compiled PHP with PCRE support. Now the same behaviour occures for the OCI8 module. Apache dies on graceful restart, only when OCI8 support is compiled in. Reproduce code: --------------- To reproduce: - Install apache-2.0.49-worker (using official SuSE RPMs) - Install Oracle 9.0.2 Client for Linux 32bit - Compiled php-4.3.7RC1 with OCI8 support using apxs2 - run 'apachectl start' - run 'apachectl graceful' and apache will die Expected result: ---------------- The expected behaviour: apache2 should not die Actual result: -------------- The actual result: apache2 dies with the following error: seg fault or similar nasty error detected in the parent process ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28603&edit=1
