[CDO 1.0] MEMStore "Concurrent modification of revision X" [message #423960]

I've been seeing a lot of these errors on the server side when a client
tries to commit (where "MyType" is one of several types in my model):

[ERROR] Concurrent modification of revision MyType@OID393v4

Should I file a bug for this?

Not sure, yet. Have you called IMEMStore.setListLimit(...)?

If not, it could be a bug but I'd need to reproduce it somehow to track
it down...

Ok, then it's likely a bug, perhaps in the MEMStore.
Can you please file a Bugzilla and describe how I can reproduce it?

Cheers
