/etc/daily problem, plus high load averages..

[Colin Leath <cleath_(_at_)_experienceartist_(_dot_)_com>]

I thought it was unusual to see load averages > 1 (actually in the 5-8
range), but I didn't notice any performance problem so I wasn't moved to
do anything about it.

Then I noticed that I hadn't received daily output or daily insecurity
output for four days (I've now changed things so I will notice sooner).

I tried running /usr/bin/sh /etc/daily, 
but it would hang during the execution of netstat, or just after.

I started killing off the old processes related to the hung /etc/daily
script. Then I found this:

 8592 p2  RN    3774:56.54 more

along with a 'more .cshrc' process that had been running for about as
long.

killing this process allowed the update db process to finish...

I think it was actually the updatedb script that was hanging because I
noticed a 'nice -5 su -m nobody' listed in the processes.

I've included relevant parts of my /etc/daily below. I modified it to
update the locate db daily.

If anyone can provide further insight into this problem, as well as
suggest how to avoid or prevent occurrences like that 'more' process
above, please let me know.

Thanks,
Colin
