[cobalt-users] "Unable to allocate" problem on raq4

Hi, this is my first message to the list so i am trying to be as
specific as I can. 

My RAQ4 is hanging every 7 days, more or less... When it hangs i can
ping but i cannot get http, ftp, ssh etc.  Rebooting solves the problem
every time, but i am worried because i think it is a memory leak or
something similar. Looking the logs the only error i see is in the error
log of apache:

FATAL:  erealloc():  Unable to allocate 15360 bytes
FATAL:  erealloc():  Unable to allocate 245760 bytes
[Thu Jan  8 04:20:54 2004] [error] (32)Broken pipe: accept: (client
socket)
[Thu Jan  8 04:20:54 2004] [error] (32)Broken pipe: accept: (client
socket)
FATAL:  emalloc():  Unable to allocate 48 bytes
Ouch!  malloc failed in malloc_block()
FATAL:  erealloc():  Unable to allocate 15360 bytes


Well, i have a lot of lines about "unable to allocate" when the box
hungs. My box has 128MB RAM, i understand it should be enough for
serving 30000pages/day, the most are php scripts. 

I have:
php 4.0.6
mysql  3.23.54 for pc-linux on i586

apache

 -D SERVER_CONFIG_FILE="conf/httpd.conf"
 -D ACCESS_CONFIG_FILE="conf/access.conf"
 -D RESOURCE_CONFIG_FILE="conf/srm.conf"

the box is also running awstats.

When i compare the requests for apache during the memory error 
all the php scripts should be ok, as i have do some profiling and they 
are ok. They were working on another box without problem.

Some hint? it could be a PHP version speficic problem? I have been
looking in the list for a similar problem and the only thing i read is
to try a RAM upgrade. Should i do that or you know another solution?

Thank you very much for your support.
