Cyrus dies

[Michael Loftis]

I suggest you use 'top', 'ps', and 'pstree' to find out what's running. 
BEcause obviously something is.  In Linux if something is blocking on Disk 
I/O it will push up the load average.  IT sounds almost like your daily 
cron jobs are scanning the cyrus mail spool and pushing over some cheap IDE 
drives.
