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!

    I have the exact same issue with my MBP, it is a 2008 Unibody with 4GB of RAM and thatI have recently upgraded from 10.6.8 to 10.7.2.

    I have noticed that every second Sunday evening, when I'm surfing the web, Sophos is running a Time Machine backup starts the whole laptop will freeze requiring me to power off the latop.  When it comes back up, I look through the Hang logs for Firefox within the Console utility and see that Sophos is listed near the bottom of the log.

    This isn't really acceptable, as I have used various Sophos products in very large corporate environments (around 2000+ seats) and never had an issue before.

    I will have a look at excluding the external backup drives from the On-Access Scanner's configuration and see how things go.

    Can I ask when the developers expect to resolve this issue and release the fixed application?

    Many thanks in advance,

    Kind regards

    You can see Andrews update from 10th November that shows they have a bug being tracked and expect it to be resolved next year in 8.0 (see below).

    I've got feedback from Dev: There is a known issue they are tracking against DEF73069;

    due to the location of the fix, it's targeted for the 8.0 release, which is due out sometime next calendar year. 

    The current workaround is to exclude the path to your time machine backup.

    Still doesn't answer why it only hits some setups, but at least it'll be fixed.

    Thanks for the re-post, its not really an answer to my question...  I would appreciate a little more information, as I use my machine every day for business critical activities

    It is strange as its only some configurations, as my configuration is a MBP that started off as 10.5, got upgraded to 10.6 and now 10.7.2.  You are welcome to logs from my machine to assist with the understanding of the issue (I just need to know where to send them).

    I thought it was an issue with a Firefox plugin, so removed them and then moved to using Safari but would like to go to using Firefox.

    I will update my configuration and see how it works.

    Thanks

    Hello, I have excluded the usual Volumes: Time Machine Backups and the wireless Airport Extreme drive it is on. I haven't been able to find Volumes/Mobile Backups while backing up with Time Machine, even with hidden files shown. My computer is still crashing. Any ideas? I am using a MacBook Pro on Lion.

    I believe you also have to exclude /.MobileBackups/ which is the actual path to the backup folder. /Volumes/MobileBackups/ is actually an NFS share of the other folder.

    Andrew - thank you for posting about excluding the Time Capsule data file on the 2TB Airport Extreme 4th gen.  That seems to have done the trick for a Macbook Air 10.7.2.  Love the antivirus - picked up loads of viruses that McAffee missed when I changed over. Happy New Year to the Sophos gang!

    Before doing this I had to look up how to "show hidden files" in the Sophos dialog box, and so thought to document this for future readers. When the dialog box opens after clicking the "+" to exclude a file, type "Cmd-Shift-." (that's a period), which allows you to see and exclude the files mentioned here.  Typing the key sequence again toggles this mode back off.

    Hi Andrew... just wondering if you heard back from Dev yet as to when the 8.0 release is targeted for and if DEF73069 will be included in that release?

    Thanks!

    DEF73069 has been marked as fixed for the next release, but I can't say any more than that at this time.

    Andrew... I see v8 is now available... Can you please confirm that DEF73069 made it to v8, so when I install it I can remove the workaround?

    Many thanks!
