Applies to:
Oracle Application Server 10g Enterprise Edition - Version: 10.1.2.0.2 to 10.1.2.2.0
Oracle HTTP Server - Version: 10.1.2.0.2 to 10.1.2.2
Generic Linux
Checked for relevance on 12-May-2009
Symptoms
Intermittently Oracle HTTP Server cannot be stopped and started using OPMN. For example:
and/or
$ORACLE_HOME/opmn/bin/opmnctl restartproc ias-component=HTTP_Server
just hangs. There are no errors. The OPMN HTTP_Server~1 log file just contains a line
/oracle/app/oracleas/Apache/Apache/bin/apachectl startssl: execing httpd
Further investigation, however, will reveal Oracle HTTP Server is throwing a core dump / segmentation fault immediately after startup. A stack trace from the 'core.pid' file shows the following or something very similar.
#0 0x000000008002f726 in dms_get_vhost_sensors ()
(gdb) where
#0 0x000000008002f726 in dms_get_vhost_sensors ()
#1 0x000000008002f7c8 in dms_get_vhost_type ()
#2 0x000000008002f9a0 in dms_set_vhost_type ()
#3 0x000000008002fbaa in dms_set_vhost_types ()
#4 0x0000000080021d9e in dms_init ()
#5 0x00000000800261dc in main ()
(gdb) quit
The Oracle HTTP Server may start up fine if using:
$ORACLE_HOME/opmn/bin/opmnctl startproc ias-component=HTTP_Server
(assuming the problem only reproduces when using "restartproc" opmn syntax)
or if using the deprecated command
Changes
Oracle HTTP Server is SSL enabled. The problem does not reproduce if HTTP Server is started up in non-SSL mode. In some cases a contributing factor is the existence of a large number of Virtual Hosts in the $ORACLE_HOME/Apache/Apache/conf/ssl.conf
Cause
The problem is caused by a bug in the Oracle HTTP Server MOD_DMS module code - a bug which is
specific to Linux
Bug:5871782 : OHS CRASHES WHEN RESTARTING SEVERAL TIMES WITH MANY VIRTUALHOST DIRECTIVE
(Although the bug abstract talks about the Oracle HTTP Server crashing when several virtualhosts have been added to the ssl.conf the problem may occur in an environment where this is not the case.)
Solution
The bug is fixed in OracleAS 10g Rel 2 patchset 3 (10.1.2.3)
There is also an interim patch available which can be applied on top of 10.1.2.0.2 Patch:5871782
Once the patch or patchset is applied the issue should no longer reproduce.
