swap getting consumed

[Mark Edwards]

I have posted about this problem a couple of times with not much 
response, I'm afraid, but here is a different take on it perhaps.  I 
have a 4.10p5 running and for roughly the last two months my swap space 
has been getting eaten uncontrollably.  The only clue I have is that it 
resets when I restart Apache (1.3.33), and so if I set up a cron job to 
restart Apache every day or hour the problem is contained:

Oddly, my physical memory doesn't seem to be generally affected:

I have 128MB of physical RAM and 384MB of swap.

The only clue I have with Apache is a lot of this in /var/log/messages:

Jan 21 18:25:06 lilbuddy /kernel: pid 68446 (httpd), uid 80: exited on 
signal 6

But I'm not sure what to make of it.  The only thing Google turns up 
related to those messages are notes about CodeRed virus attacks, but 
Apache 1.3.33 is suppose to address that issue.

Does anyone have any suggestion of how to attack this problem?  I'm 
totally stumped.
