Assuming hardware failure, a new physical host was set up running 10.1 but again, after a few days the same issue started occurring. After digging around a bit, I found the system was getting stuck while trying to remove the oldest snapshot folder from rsnapshots. All new processes seem to be stuck waiting on disk. If I leave it long enough, I'm no longer able to even ssh in to the system. I've since set up a local virtual host and have been able to duplicate the problems on it as well. The virtual machine is running rsnapshot to back up the same data (in this case, the vmail folder from our mail server). While running FreeBSD 10.0, I had no issues. It was able to delete the oldest snapshots and everything worked as it should. After upgrading to FreeBSD 10.1, without making any additional changes, the system hangs when running rm to remove the oldest snapshot folder. Total backup size is around 150GB. Filesystem is single HDD with UFS and no mirrors/raid. Manually running "rm -rf
