Hi, I have been using rsnapshot for years to do backups. A few days ago i realized that the backup job wasn't working anymore. Investigating I found, that rsnapshot segfaults while running. I straced the process and found out it always happens when "lstating" a file:
lstat("14-01-17-06:40:01_ps.log", Message from syslogd@g at Oct 26 11:40:47 ... kernel:[2152238.556062] general protection fault: 0000 [#32] SMP <unfinished ...> +++ killed by SIGSEGV +++

Is there any way for me to debug this further or should I check the RAM of the machine with memtest86? I'd rather not bring it down if not absolutely needed, as it hosts some services for other people.
EDIT: Thanks for all the input. I decided to check the physical RAM. Everything all right. After a reboot the problem was gone. So no idea what caused it. In case it happens again, I'll know where to start looking.
