net stop tomcat6 service hangs on Windows 2008 (64-bit)
I'm seeing a pretty consistent issue when stopping Tomcat6, when running as
a Windows service.
Repro:
From the cmd prompt type
net stop tomcat6
Results:
The Apache Tomcat service is stopping........
The Apache Tomcat service could not be stopped.
Notes:
1. Platform details:
a. Windows 2008 Server SP1 (64-bit)
b. Tomcat 6 build 18 (both with/without the native DLL = same issue)
c. JRE 1.6.0_12
2. I could find no events nor tomcat/catalina logs with a hint as to
root cause, nor did I bear fruit with a search through the FAQs, Google,
etc.
3. I tried to enable verbose tomcat logging as per
http://tomcat.apache.org/tomcat-6.0-doc/logging.html but when the issue
occurs, the pertinent info isn't as yet written to disk, since it appears
log4j flushes only during the log rollover.
4. The only workaround I have at this point is to kill the tomcat6.exe
process manually.
5. A thread dump is below if that helps.
Has anyone seen this before?
Thanks,
Matt

Hi Matt
what happens if you query the tomcat 6 service
sc query tomcat6
?

For reasons never explained, the .bat scripts are not included in the .exe download; they are in the .zip and tarballs.

I don't have a shutdown.bat or .cmd anywhere in C:\Program Files\Apache
Software Foundation. No indication in logs of an OOM situation.
I'm going to write a small batch file that attempts to stop the service,
sleeps, queries the service state with SC, and if required kills the
process.
Thanks for all the responses.

Just to share a bit of my experience:
I have seen Tomcat hanging (and unable to respond to shutdown.sh)
after an out-of-memory (PermGen). It was on Solaris.
I have not dug into it yet (as it is not so important for us), but I
can say that there are some places where an OOM is caught and ignored
or wrapped. The one that showed in our logs was Spring Framework's
DispatcherServlet, but Tomcat itself does the same: merely throwing
an OOM Error results in the usual "HTTP Status 500" error page being
shown.
If you face such a situation, then "simply killing tomcat6.exe process
if net stop fails" would be the only recipe that I know should be
working.
If your case is different, e.g. you failed to stop a Tomcat instance
that was not hung, then maybe some other cause and a suitable
solution/bugfix can be found. E.g. if it is the case of Application
threads that are not terminating, that Charles mentioned in his first
reply. And in my case of OOM, some tuning can lessen the probability
of it.

I have only the thought of obtaining some diagnostics before killing
it, like getting the Java stack (using jstack tool from JDK, or from
the menu shown by tomcat6w tray icon), or waiting until log4j flushes
the logs.

Refresh our memories - does the hang still occur if you use the shutdown.bat script rather than net stop?

Never heard back from anyone, and I'm left assuming this is a bug, albeit a
difficult one to isolate.
We did try a less intrusive workaround by using a timeout on the Shutdown
tab in Tomcat properties, to no avail.
I guess we'll stick with the less elegant workaround, simply killing
tomcat6.exe process if net stop fails, unless anyone can think of something
else to try.

No JNI.
The process dump immediately below shows JVM still loaded, etc. I then
drill into some of the threads via Process Explorer further down. Sorry for
length of this post, not sure what would help / not help, but I didn't spot

No JNI.
The process dump immediately below shows JVM still loaded, etc. I then
drill into some of the threads via Process Explorer further down. Sorry for
length of this post, not sure what would help / not help, but I didn't spot
anything obvious...

Ok, rules that out. Do any of your webapps make use of JNI? Might want to use Process Explorer to see what's still going on inside Tomcat.

The usual cause is extra non-daemon threads started by a webapp that does not properly manage them; any such extra threads will not allow the JVM to terminate. However, your thread dump does not show any to be present.

Since all threads are suspended, it's looking a bit like a JVM problem. I've had no problems starting and stopping a Tomcat 6 service on Vista 64 using any of the Services snap-in, tomcat6w executable, or net start/stop, using JDK 6u14; you might try a later JVM.
