Summary: Tomcat hangs on shutdown
Product: Tomcat 6
Version: 6.0.14
Platform: PC
OS/Version: Windows Vista
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: cowwoc@bbs.darktech.org
JDK 1.7.0-b23 (32-bit build)
Quad-core 64-bit CPUs
Windows Vista 64-bit
Tomcat seems to hang randomly (approximately 10% of the time) on shutdown if I run:
net start tomcat6
net stop tomcat6 (this fails)
I have the following clues for you:
1) This is not reproducible using startup.bat/shutdown.bat scripts.
2) This is not reproducible without APR.
3) I didn't run into this problem back when I was running Tomcat 6.0.13, single
core 32-bit CPU, same JDK build, with APR installed. Unfortunately, I can't go
back to this hardware because it's gone.
4) The last line in the log reads: "INFO: Stopping Coyote HTTP/1.1 on http-80"
so it looks like it was in the middle of shutting down but something caused it
to hang.
I wanted to debug this further unfortunately I'm not sure how to get you guys a
stack-trace or thread-dump when running Tomcat as a service.
I suspect that something in the native libraries (APR) is at fault. Consider the
fact that I moved to a multi-core CPU, perhaps the APR code has some sort of
race condition that is triggering this. Can you please suggest how I can
generate more debug information for you to investigate? Ideally I'd like to get
a thread-dump at the time of the hang.

This issue needs further debugging to identify where the root cause is. The best
