clogd can seg fault
Last modified: 2010-01-11 21:09:39 EST
The cluster log server can seg fault. This means that the kernel can no longer communicate with userspace and get any work done.
If a mirror was started and then suspended very shortly after, the list of pent-up requests waiting for a checkpoint would be freed. If one of those requests was POSTSUSPEND, it would be processed and would also try to free the list of pent-up requests. Since this action was nested, the outer function would segfault because the list it was processing was free out from under it.

I have not seen any seg faults with the latest rpms, marking verified.
