[jira] Commented: (DERBY-614) Execution failed because of a Distributed Protocol Error

    [ http://issues.apache.org/jira/browse/DERBY-614?page=comments#action_12360015 ]

--------------------------------------

I committed this patch 

Date: Fri Dec  9 17:51:26 2005
New Revision: 355689
URL: http://svn.apache.org/viewcvs?rev=355689&view=rev


Thanks so much for the wonderful fix and the great javadoc you added. 

One thing I did notice that deserves followup and may be related to the intermittent hangs you have seen,  is that there was a finalizeChain() call in the old file on line 6139 that seems to be missing from the new version,  line 6278.
This might be the source of the hang you reported for one of the dss chaining bugs  (I can't seem to find that mail now).

Can you take a look at that and also clean up the out of date patch attachments to 614.

Yes, I will follow up on both these items.

Thank you very much for reviewing and committing the patch.
