Thanks everyone for their suggestions. Unfortunately, that doesn't help me with my particular issue. I have a memory leak in one of my apps, and when the system runs out of memory, it stops responding to new requests. I have a script that will detect this condition and automatically restart Tomcat. I was hoping to add a jstack command to this script to give me a thread dump prior to restarting Tomcat to give me better troubleshooting information. Your solution would work under normal circumstances, but I don't know how to script a ctrl+break. ;-)
