Description Onno Van den Troost

2010-12-15 21:40:03 EST

We applied OpenRSE 11-05 build to resolve Bug 328060 (backport 329259 and 328154) "command queue in Miner should be synchronized".

Now we notice a NPE on the RDz client when doing a rename or delete of a remote member.

Onno, I think Masao indicated in the work item that the NPEs have nothing to do with the server.

Further investigation by development shows that the root cause is a racing condition on the client, so not related to the RSE server code at all. We just happen to run into it now.

case closed.
