Jstack and Not enough storage is available to process this command

Question

I\'m trying to run jstack command on my java application. Application is rather big, running inside jboss AS occupying about 4gb of memory. OS is Windows Server 2003 Standar

Answer 1

In the past I have seen this when the JVM is running as a Windows Service on Windows 2003.

First, check to see if this is an issue with the TMP directory.

Second, jstack (or the other utilities like jconsole) will not connect to the local process unless it is running in the same session. If the service is running as a specific user, you may be able to connect by logging into the same session. If you are using Remote Desktop, you can connect using "mstsc /admin" (used to be /console) and try to run jstack again. Definitely check to make sure the TMP directory is set properly if this doesn't fix the problem.

If the service is running as LocalSystem, the above procedure probably will not help much. I don't know if there is a way to log into the same session as LocalSystem.

Some other alternatives may be to set the process up for remote monitoring and use jvisualvm (from the server itself or another machine) to connect over a port and do a thread dump.
