PHP itself works fine with MPM, as far as anybody knows. But one of your --enable-xyz may NOT work fine with MPM! PDO is "new" and suspect. "mbstring" is on the way out in favor of PHP 6 Unicode, and I think it's also suspect. OCI8, well, I dunno... You'd think enough folks would be using that to get rid of all the thread-bugs, but... > ----------------------------------- > #0 0x007937a2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2 > #1 0x007d7c96 in kill () from /lib/tls/libc.so.6 > #2 0x08070da8 in sig_coredump () > #3 <signal handler called> > #4 0x00a00d24 in pthread_mutex_lock () from /lib/tls/libpthread.so.0 > *#5 0xb461d9f5 in tsrm_mutex_lock (mutexp=0x0) > at /ade/rbadan_gollum/oracle/apache_modules/mod_php/php-5.2.1 > /TSRM/TSRM.c:660 > #6 0xb461d071 in ts_resource_ex (id=0, th_id=0x0)* > at /ade/rbadan_gollum/oracle/apache_modules/mod_php/php-5.2.1 > /TSRM/TSRM.c:345 > #7 0xb472dcb5 in php_handler (r=0x85c65b0) > at /ade/rbadan_gollum/oracle/apache_modules/mod_php/php-5.2.1 > /sapi/apache2handler/sapi_apache2.c:500 > #8 0x080829af in ap_run_handler () > #9 0x08082807 in ap_invoke_handler () > #10 0x080976d5 in async_run_handlers () > #11 0x080975f3 in async_process_connection () > #12 0x08097346 in process_socket () > #13 0x08096e97 in worker_thread () > #14 0xb7f83e33 in dummy_worker (opaque=0x85bf438) at > threadproc/unix/thread.c:142 > #15 0x009ff371 in start_thread () from /lib/tls/libpthread.so.0 > #16 0x008779be in clone () from /lib/tls/libc.so.6 You probably should post this into: http://bugs.php.net It is a pretty cogent error report. If you can provide source code for the tests that make this segfault, then odds are extremely good that somebody on the PHP Dev Team can reproduce it and fix it. -- Some people have a "gift" link here.
