I'll take another closer look at the stacktrace, but from before and just glancing now, I don't see any ongoing Ice methods.

what I was indicating was that in the shutdown hook we are trying to shut down running client, if a long method has not yet returned e.g. long image rendering or a longer search, the application will freeze until the method returns. The freeze could have been due to change group or a a switch user and the proxies being deleted.

J-m, so are you thinking that there was a blocking method, then application exit began, a hang occurred, and then that method exited?

That's what I suspect.

- Milestone changed from 5.1.0-m1 to 5.1.0-m2
Let see if we can find the source of the problem

- Milestone changed from 5.1.0-m2 to 5.1.0-m3
Moved this to m3. Maybe it could also be closed? Didn't see this error happening anymore.

- Resolution set to invalid
- Status changed from new to closed
Set to invalid, not reproducible.
As JM mentioned: This probably wasn't a deadlock, but a ICE operation which cannot be cancelled.
