apache exiting on signal 6

[Joe Auty]

Hello,

I've seen a lot of information on Google about this error message  
I've been seeing a lot of in my logs:

> pid 11443 (httpd), uid 80: exited on signal 6
> pid 11454 (httpd), uid 80: exited on signal 6
> pid 11447 (httpd), uid 80: exited on signal 6
> pid 11442 (httpd), uid 80: exited on signal 6
> pid 11527 (httpd), uid 80: exited on signal 6
> pid 11525 (httpd), uid 80: exited on signal 6
> pid 11523 (httpd), uid 80: exited on signal 6
> pid 11756 (httpd), uid 80: exited on signal 6
> pid 11755 (httpd), uid 80: exited on signal 6
> pid 11828 (httpd), uid 80: exited on signal 6

Many of these pages point to resource limits issues, but I'm a little  
puzzled.

I do have some httpd processes that have been taking around 30 - 40%  
of my CPU (although not constantly), but I believe I generally have a  
decent amount of free RAM (my snmp daemon doesn't seem to log memory  
consumption, unfortunately).

# limits -d
Resource limits (current):
   datasize           524288 kb

If this is a resource limits issue, what is the best way to track  
down this issue? I have tried raising Apache's MaxClients, but this  
hasn't helped.

I've also seen some info which suggests that this might be an Apache  
bug of some sort, but I've seen this in both Apache 1.3 and 2.0.  
Right now, I'm running 2.0.59 with eAccelerator.

I guess the next step might be to try disabling eAccelerator... I'll  
let you know if this helps. In the meantime, if you have any other  
suggestions they would be welcome!
