Another process (thread) is applying transactions for this client:

Question

Has anyone seen this error
'Another process (thread) is applying transactions for this client: MNEWMAN Try again later.'
We seem to be getting a few upload transactions put into the error queue for this reason, sometimes just executing the transaction clears it, but more often the data actually looks to have been correctly posted to the server as well as appearing in the error queue, as itf two threads have picked up the same transaction, one has applied it without error and the other failed
any ideas?

Answer 1

latest update from Oracle is to
1.Set MAX_APPLY_TRIES=5
2.Set APPLY_TRIES_DELAY=10
Done this, but waiting for sufficient activity to see if it solves the problem.
I had thought about knocking max_threads down to 1 (and might do this to try and isolate some odd performance issues), but the problem is that this would make the apply and compose process take three times as long (we use 3 threads), and that will not be acceptable for long on the live system
