CSF/LFD xenserver vm lockup?

    Does anyone have csf/lfd installed on a xenserver centos vm without experiencing random lockups?

    It would happen maybe twice/month, nothing in logs... once locked up, the cpu would be pinned (if multiple cpu, one would be pinned).

    Happened on about 10 VMs. Each running latest CentOS 5.7, about half with cpanel. They were also using the cluster option.

    Once csf was uninstalled the lockups stopped.

    There is a thread about it on the csf support forum but it's a little old w/ no remedy.

    Other notes: System is running xenserver 5.5, all VMs had xentools installed, xen kernels..

    Its been a couple months since I removed it - just wondering if anyone else has experienced this and if you found the fix.

    BTW, this seemed to have cleared up after we upgraded our xenserver pool from version 5.5 to 6.0. If you're having this issue, upgrade and see if it fixed it for you.
