Hi, this really sounds weird. In order to audit it, the following checklist
might help:
1. If the system was administered by an admin other than you and he got
fired/dismissed with hard feeling on him, he might put a crontab that would
do nasty thing randomly. Audit all the files in:
/var/spool/cron
/var/spool/at
Also all the script in /etc/cron.{d,daily,weekly,monthly}, /etc/crontab
2, Audit all RPM files installed using:
rpm -Va, looks for a difference in md5sum for binary files such
as /bin/ls,/bin/ps, etc. You might want to use cracker detection script such
as rkhunter.
3. Looks for the word "error" in log files:
grep -r error /var/log
See for related error such as filesystem corruption, etc
4. It's a long shot, but could be a misconfigured rsync script?
HTH, pls let us know the result.
