The load and waiting on I/O is definitly suspicious. Maybe something like a cronjob running updatedb for locate ? /etc/updatedb.conf holds the paths that should be excluded if you don't want to turn it off completely. As they are both doing a lot of disk activity it will slow down rsync. I suggest having a good look at syslog looking for CRON and/or check: /etc/crontab /etc/cron.d/ /etc/cron.hourly/ /etc/cron.daily/ /etc/cron.weekly/ /etc/cron.monthly/ /var/spool/cron/ ------------------------------------------------------------------------------ Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!
