http://nagoya.apache.org/bugzilla/show_bug.cgi?id=17831 worker mpm sometimes fails to terminate child processes Summary: worker mpm sometimes fails to terminate child processes Product: Apache httpd-2.0 Version: 2.0.44 Platform: Sun OS/Version: Other Status: NEW Severity: Major Priority: Other Component: worker AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] The worker thread sometimes fails to terminate child processes resulting in the following error in the apache error_log. [Thu Mar 06 19:36:05 2003] [crit] the listener thread didn't exit [Thu Mar 06 19:36:06 2003] [crit] the listener thread didn't exit [Fri Mar 07 00:10:02 2003] [crit] the listener thread didn't exit [Fri Mar 07 06:05:25 2003] [crit] the listener thread didn't exit [Fri Mar 07 06:05:26 2003] [crit] the listener thread didn't exit >From reviewing the code in server/mpm/worker/worker.c it looks like the main process atempts to send a SIGHUP to the child 10 times over a 5 second period. If that fails the child process never terminates. This eventually leads to the server hitting its ServerLimit and ultimately denying requests. This was noticed while using Apache-Tomcat mod_jk 1.2 from CVS. I suspect that if mod_jk is waiting more than 5 seconds to read a response from the Tomcat connector while the main process is trying to signal it to terminate the child process termination fails. I am not sure if this is something that can be fixed in httpd 2.0, mod_jk, or both. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
