Receiving intermittent error within 1-20 minutes after starting / restarting Apache2 server when any given random OCI function call against an Oracle9 database server occurs. NOTE: firewall exists between the Apache host server and Oracle server (suspect and cannot test bypassing firewall due to extended policy process at organization): PHP Warning: Unknown: _oci_close_session OCIHandleAlloc OCI_HTYPE_SVCCTX: OCI_INVALID_HANDLE in Unknown on line 0, referer: [http://mysitex.domain.com/something.php] Unknown(0) : Warning - Unknown: _oci_close_session OCIHandleAlloc OCI_HTYPE_SVCCTX: OCI_INVALID_HANDLE TEMPORARY DIAGNOSIS AND STRATEGY UNTIL FIREWALL CAN BE BYPASSED FOR FURTHER TESTING: We were using: http://www.php.net/manual/en/function.session-set-save-handler.php We are now using: Turning off database management of session related info and enabling following in PHP.INI: session.save_handler = files session.save_path = /tmp (a writeable directory by Apache5) (then confirming that session related temporary files are being opened in session.save_path) Ploblem no longer occurring at present. (36+ hours) Believe it is a firewall or OCI connectivity issue with the Oracle server. Question: With the included TraceLog (minus the GDB error), can we avoid from a PHP source perspective, an Apache2 segfault? It may be awhile before we can ascertain what causes this problem such as the suspected firewall between servers or some process on the web server that may be interfering. Reproduce code: --------------- Intermittent issue - not consistently reproducable. Actual result: -------------- Program received signal SIGSEGV, Segmentation fault. 0xfdcd27e4 in _oci_close_session (session=0x2e8c68) at /usr/local/src/php-5.0.2/ext/oci8/oci8.c:2941 2941 CALL_OCI_RETURN(OCI(error), (gdb) bt #0 0xfdcd27e4 in _oci_close_session (session=0x2e8c68) at /usr/local/src/php-5.0.2/ext/oci8/oci8.c:2941 #1 0xfdccc368 in _oci_session_list_dtor (rsrc=0x2d1ab0) at /usr/local/src/php-5.0.2/ext/oci8/oci8.c:1124 #2 0xfdeed8b8 in list_entry_destructor (ptr=0x2d1ab0) at /usr/local/src/php-5.0.2/Zend/zend_list.c:178 #3 0xfdeea414 in zend_hash_apply_deleter (ht=0xfe0f0b10, p=0x22aa18) at /usr/local/src/php-5.0.2/Zend/zend_hash.c:574 #4 0xfdeea7c4 in zend_hash_graceful_reverse_destroy (ht=0xfe0f0b10) at /usr/local/src/php-5.0.2/Zend/zend_hash.c:640 #5 0xfdeedb34 in zend_destroy_rsrc_list (ht=0xfe0f0b10) at /usr/local/src/php-5.0.2/Zend/zend_list.c:234 #6 0xfdec711c in shutdown_executor () at /usr/local/src/php-5.0.2/Zend/zend_execute_API.c:285 #7 0xfdedd0b0 in zend_deactivate () at /usr/local/src/php-5.0.2/Zend/zend.c:818 #8 0xfde66bb8 in php_request_shutdown (dummy=0x0) at /usr/local/src/php-5.0.2/main/main.c:1212 #9 0xfdf29d68 in php_apache_request_dtor (r=0x1edbf0) at /usr/local/src/php-5.0.2/sapi/apache2handler/sapi_apache2.c:435 #10 0xfdf2a58c in php_handler (r=0x1edbf0) at /usr/local/src/php-5.0.2/sapi/apache2handler/sapi_apache2.c:553 #11 0x00046388 in ap_run_handler (r=0x1edbf0) at config.c:151 ---Type <return> to continue, or q <return> to quit--- #12 0x0004692c in ap_invoke_handler (r=0x1edbf0) at config.c:363 #13 0x00033c74 in ap_process_request (r=0x1edbf0) at http_request.c:246 #14 0x0002f15c in ap_process_http_connection (c=0x1e2bd8) at http_core.c:250 #15 0x000519ec in ap_run_process_connection (c=0x1e2bd8) at connection.c:42 #16 0x00044c7c in child_main (child_num_arg=1969000) at prefork.c:609 #17 0x00044e5c in make_child (s=0x99950, slot=0) at prefork.c:649 #18 0x00044ee0 in startup_children (number_to_start=4) at prefork.c:721 #19 0x000456a0 in ap_mpm_run (_pconfstabsread.c:624: internal-error: sect_index_data not initialized A problem internal to GDB has been detected, further debugging may prove unreliable.
