Re: [Wrapper-user] Service started with Java Service wrapper becoming stale during server reboot

[Christian M. <chr...@ta...>]

Hello Divya,

how is your script starting/stopping the processes exactly?

The wrapper-script whenever called to start an instance, checks for the
pid-file, which contains the pid of the Wrapper process.
If the pid from the file matches with the currently running processes, then
it won't start the Wrapper, since it assumes the process is already
running.
The warning "Removed stale pid file", means that the pid in the pid file
doesn't match. So the script removes the file and starts a new instance.
The Wrapper removes the pid file by itself usually during exiting, however
if the Wrapper is forcibly killed (like a kill -9), then it won't have a
chance to remove the file.
So when you run the start command after the reboot and see the stale pid
warning, it means probably, that the Wrapper was forcibly killed during
shutdown and couldn't remove the pid file.

could you also please turn on debug log level (wrapper.debug=TRUE) and
re-run?

Best Regards,
