I'm sure it's something I've done...I just don't know how to interpret
what I'm seeing here in the jstack output (see below). Any help would
be greatly appreciated.
Thanks,
Lon
Here is the jstack stuff for just the deadlock (since the list
wouldn't allow the full file):
Found one Java-level deadlock:
=============================
"WorkerThread255":
waiting for ownable synchronizer 0x00002aaab421aef0, (a
java.util.concurrent.locks.ReentrantLock$NonfairSync),
which is held by "WorkerThread9"
"WorkerThread9":
waiting for ownable synchronizer 0x00002aaac0ecc338, (a
java.util.concurrent.locks.ReentrantLock$NonfairSync),
which is held by "Finalizer"
"Finalizer":
