Hi Experts,
After our app started for a while, we got warnings in wls admin console, saying that there are stuck threads. And during the 2-hour spec run, this thread is the only stuck thread.
Attached is part of server log and thread dump related to this stuck thread. Any help would be really appreciated.
Thanks,
Candy
