Macbook Air with Lion freezes during Time Machine backup...

floridabrits

I see a number of threads here with folks having stalling systems, but I have a situation where my Macbook Air completely freezes up (usually when Time Machine backup starts, or that's what I have observed when I wake the system up... the system wakes up, then freezes as Time Machine backup starts).

I logged a case with Apple and since they told me to remove Sophos Antivirus and since then my system has completely stabilized and I've not had a freeze in over a week (prior to uninstallation of Sophos my system was freezing up between 1 and 5 times a day).

Any ideas 'why' this is happening and if Sophos are aware of this and looking to patch/fix it?  Has anyone else experienced this issue and is it possible to run Sophos on Macbook Air/Lion or is there a compatibility issue?

Many thanks for any help/pointers!

    You wouldn't happen to have disabled virtual memory would you?  This is exactly what I would expect to happen with virtual memory disabled.

    ----- How would I know/how do I check this?   I haven't done anything specifically to change anything with the memory, so 'probably' not...

    If you haven't, what happens if you add /private/var/vm/ to the exclusion list?

    ---- I could reinstall and try this for sure.

    You may also want to exclude your TimeMachine backup drive/folder to see if that helps.  I'm figuring that if you keep on-access scanning enabled and have scanned your backups already, it's unlikely they'll become infected.

    ---- Again, I could reinstall and try this, but my Mac mini is running Sophos straight 'out of the box' with no exclusions at all (including my Time Machine backup drive) and it doesn't cause any issues, so wondering why the Macbook Air would be different?

    Thanks...

    Once I hear back from you I can reinstall and try again with these changes...  I have just uninstalled using the 'Sophos Uninstall' in Applications, so are there any other files/folders I should delete to ensure a 'clean/fresh' install?

    Thanks again...
