Thanks. Good point.

As an aside, this weekend has been a bizarre weekend. After finally
resolving this "lost ticks" issue, another server kernel panic and crashed
mysteriously, and again kernel panic upon boot up.. some messages about bad
memory in DIMM8 and DIMM7. then my friend's Drobo went all red and failed
this afternoon. We must be getting showered by intense cosmic rays this

thanks for the responses from everyone.
