WARN - ThreadPoolAsynchronousRunner$DeadlockDetector.run(429) |
ousRunner$DeadlockDetector@547c38 – APPARENT DEADLOCK!!! Creating emergency
threads for unassigned pend
I found on the net that this is related to c3p0 pooling software and is fixed
in c3p0 0.9.0.2. I see that xwiki is using c3p0 0.8.
Do you think this is right?
