I've had a similar problem occur on my machine, where Zimbrahelper used all available memory and was up to about 2Gigs of VM before I killed it.
For me, the answer involved setting Sync to manual, Resetting my Sync Data, and then restarting the machine before setting automated synchronization again.
I suspect the short answer might be 'kill the ZimbraHelper process and reset your Sync Data'. Hope this helps. |
