Customer has a broken exchange and we are migrating them over to Zimbra, Their profiles allow us to grab the info off their OST files in outlook and that seems to be working fine. The problem we had last night was Zimbra MST seemed to have crashed while running the migration on some of the larger mail boxes. I need to sort through the logs but MST crashed as soon as we started the migration so it seems linked at this point. Is there anything I can do config wise to stop this from happening? I have not touched any of the defaults in the server for message handling. I am running Zimbra 8.0.6_GA_5922.FOSS with Zextras 1.8.12. The server is pretty low usage 35 users so far running fine day to day.

The server has 8GB of RAM and a is a Quadcore Opteron VM.
