I would be inclined to patch to the latest 1.0 build first, as Simon says, build 290. Once you have confirmed that is happy, move to 1.1.1, which was just released, via the Patch CD.
System requirements of v1.1 says that "This patch/file is for Novell Data Synchronizer Mobility Pack 1.1 and is to be used only if Mobility Device Management by Notifycorp is being used"
We are still using v1.0 build 290, but there are so many issues with it that we need to at least try to fix them and as far as i know, there is nothing else we can do ath the moment, but to update to v1.1.1 and hope for the best.
Fortunately, The Auto-Vacuum Daemon monitors table activity and performs VACUUMs and ANALYZEs when necessary
Just updated to v1.1.1 using "Patch CD Update" method. Looks like everything is working fine now, but i'm guessing that pretty soon some users start sending emails saying that their devices no longer sync some or all items etc, just like before. :-(
