are they using the same file system?

I would suspect file system corruption. Is the trash directory empty when the freeze occurs? In general, I'd suggest an 'fsck', but with a BackupPC pool that might not work. You *could* try moving the trash directory out of the way and recreating it with the same permissions. This would avoid accessing a problematic file within it, supposing this is causing the problems. Though, normally, I'd expect something in the system log files in case of a file system panic. Well, 'df -T' might tell us more.
