Hi all Debugging Experts on EditingContexts,
I have some weird locking-problem which on an irregular basis leads to
following exception:
ERROR #1:
[2005-12-05 10:14:18 CET] <Finalizer> Unable to release locks held by a
deallocated EOEditingContext.
[2005-12-05 10:14:18 CET] <Finalizer> java.lang.IllegalStateException:
Illegal Lock usage: unlock() called without a lock().

Does anyone know which error might be behind this obscure message? I did not
see any reference to my code in the stacktraces. Anyone experienced
something similar?
Some backgroundinfo: This is a WO-app with usually about 10000 requests per
day. Several users (up to 60 in parallel) are using the app which is running
with one instance in concurrent request handling mode.
