IDEA-47468 idea unable to kill stuck tomcat process

Issue is visible to: All Users

On linux, when the tomcat process gets stuck, idea is unable to kill it

For example when there's a PermGen leak, after reloading a webapp a number of times, it will throw a Java.lang.OutOfMemoryError: PermGen space, and the process will be completely stuck, so the only way to fix the problem is to manually kill it ( kill -9 that is ) from the command line.

This is real annoying since in some cases there's such permgen leaks cannot be avoided (when using AspectJ runtime weaving for example)

I was under the impression there was a 'kill process' button (skull icon) in addition to the normal stop (cross), but i haven't seen it in a long time (maybe it's windows only?)

Environment: Linux (Ubuntu 8.10)

Using java API is not possible to kill the process "reliably". The "kill process" button was implemented using debug API and was available only when you debugged the application. Currently its functionality is available as a part of the "stop" button (like it was before) so the skull button was made redundant.

But the 'stop' button doesn't seem to kill stuck processes, even when run in debug mode, is it supposed to, or there is just no way to kill it ?

Currently "Stop" button for Tomcat configuration runs the shutdown script so if the tomcat process gets stuck it won't be killed. I think we will fix the problem in the following way: after pressing 'Stop' button IDEA will wait for 10-20 seconds and if the server process is still alive IDEA will try to kill it by destroying the process or by using debug API.

That sounds better, but could you please add the ability to force the kill before the the timeout.

For example the 'Stop' button instead of graying out could change to a 'force' kill mode that could be clicked again to immediately kill it, rather than having to wait 10-20sec when you already know it's not going to work (like when the server blew up with a PermGen exception for example)

I restored 'Kill process' action for application servers. It works via debug API in debug mode and destroys the process in 'Run' mode. So I think this problem is fixed.
