I have quite a few segfaults on my production servers.
The crashes occur on :
#0 0xb78f3779 in _oci_close_session (session=0x8382a20)
at /soft/sources/php/php-5.0.4/ext/oci8/oci8.c:2961
2961 CALL_OCI_RETURN(OCI(error),
where
(gdb) print *session
$1 = {num = 137800016, persistent = 0 '\0', is_open = 253 'ý',
exclusive = 49 '1', thread = 8 '\b', sessions_list = 0x0, server = 0x0,
pSession = 0x0, pEnv = 0x0, charsetId = 0}
At the same time, I have :
[29-Jul-2005 07:57:41] PHP Warning: Unknown: _oci_close_session OCIHandleAlloc
OCI_HTYPE_SVCCTX: OCI_INVALID_HANDLE in Unknown on line 0
I use my oci8 ping_freq patch
(http://www.jeuxdecartes.net/static/oci8.ping_freq.patch) - that explains the
line numbering difference.
(more info on http://bugs.php.net/bug.php?id=33915)
This small fix corrects the crash (there could be a problem somewhere else -
why do I have a session without a server ?) :
