No, it doesn't. It sometimes does. For instance we have a scripts which rotates the apache logfiles once a month. I think we have about 50 tomcats (distributed across a number of servers) of which 3 went down last month after the logfile rotation (which uses the kill -HUP command explained earlier). Also when we restart apache by hand (after configchanges) this sometimes happens. > - Does it happen at the exact same time? No. It also happens after config changes which are made a random times. > If so, you can start strace against the Java process and stop httpd. > Then check in the strace output (write to a file), whether you can > either see a signal sent, or a connect on the Tomcat shutdown port. > > A slightly similar thing I once saw was people starting Tomcat > interactively with a shell, that did not have job control and sent some > signal to all child processes, when the user terminated the shell, > resp. logged out (I think it was ksh on Solaris at that time). I will try and obtain more logging. Seeing it happens at undetermined times this might prove to be challenge by itself.
