I've got an odd thing going on here. I have 2 tomcats running on a windows 2003 64bit server. When I use jstat to grab the gc information it just says: not found. I pass it the pid, it says not found. When I pass it zero as the pid it find "something". But that something seems to keep changing. Is there a way to get and pass the correct vmid on windows? When I try passing one as the pid it says not found. So I'm not sure what zero is doing but it's doing something.
