Description Matthieu Patou 2013-01-25 07:30:10 UTC
During make test message appears:
IRPC callback failed for DsReplicaSync - NT_STATUS_IO_TIMEOUT

The cause of the problem is that in standard model 2 process can end-up creating the same messaging socket that is used to send back the IRPC result.
The process that has sent the request will wait for the response to come before removing this socket but the other process can have already remove it preventing the response to be delivered.

Karolin, can you pickup this patch for next release (4.0.2 if not too late).

It's from andrew and I reviewed it.

I'll replace with the identical patch with cherry-pick references once this autobuilds.

Just the same patch, but with the cherry-pick stuff.

An additional patch for the single_task function will probably follow.
