Hi,
Twice we've encountered out of heap space errors lately. This time I
remembered to try and use tools like visual vm to diagnose. I opened
Visual VM and it only showed the Java process of Visual VM itself, not
the java process running GlassFish. I tried the remote feature but that
didn't help. I tried using remote desktop's /admin option to get me to
the real console, and that didn't help.
I was able to get a stack and heap dump, but only after logging in using
remote desktop's /admin command.
Any idea how I can use Visual VM to diagnose GlassFish? I've since
increased the heap size to 1 GB (from 512 mb) and am going to try to
analyze the heap dump from NetBeans.
Thanks,
Ryan
