Subject RE: Tomcat 6 shutdown hangs server when using JDK 6.0_15
Date Tue, 11 Aug 2009 13:51:46 GMT
Thanks Filip for the reply, but as I said in my original post, this is running on a virtual
machine, so hardware isn't a factor. In addition, this only started when I began using JDK
6 instead of 5, and only continues to happen if I use JDK 6. If I use 5, there's no problem.

I will test this on another VM and a non-VM system to see if they behave the same way, but
I would still appreciate more input if it's available.

Thanks in advance!

if you entire server dies, then it sounds more hardware related, could 
be software triggered, but no, tomcat shouldn't kill your system :)

I attempt to shutdown any tomcat instance, the entire server (VM) hangs and has to be rebooted.
Even out of the box tomcat installations cause this.

useful. I've attempted to use jstack and pstack to get a trace of the process during shutdown,
but the server dies before anything useful is logged. Has this happened to anyone else out
there? Google yields lots of "tomcat hung" hits, but nothing about the OS hanging in response
to a shutdown.
