I instaled the latest isync connector 6.0.5GA2169 on Mac OS X 10.6.2 10C540. Within 1 hour my system had ground to a near standstill. Looking at the running processes I discovered AddressBookManager was consuming 9.6GB of memory. I killed it and the system recovered. About 30 minutes later the system started to act sluggish. I check and AddressBookManager was back consuming 3.3GB of RAM. This behavior persists across reboots. Has anyone seen anything similar?
