I have been having issues running BOINC on Macs running Leopard 10.5.2.

It just randomly quits whenever it feels like it. I am running the latest version 5.10.45 for Mac, and this has happened before with older versions as well. I have reinstalled the client, repaired permissions, etc... This is happening randomly on various machines so I doubt there is anything wrong with the hardware.

This is from system.log
