Hello,


Here is : /proc/meminfo:


	squid@proxy1:/root$ more /proc/meminfo
	total:    used:    free:  shared: buffers:  cached:
	Mem:  1058295808 1040723968 17571840        0 125198336

Here is  /etc/profile :
 	squid@proxy1:/root$ more /etc/profile
	# /etc/profile: system-wide .profile file for the Bourne shell
(sh(1))
	# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).
	 
	PATH="/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games"
	 
	if [ "$PS1" ]; then
	  if [ "$BASH" ]; then
	    PS1='\u@\h:\w\$ '
	  else
	    if [ "`id -u`" -eq 0 ]; then
	      PS1='# '
	    else
	      PS1='$ '
	    fi
	  fi
	fi
	 
	export PATH
	umask 022
	


proxy1:~# su squid
squid@proxy1:/root$ ulimit
unlimited



and :
squid@proxy1:/root$ more /etc/default/squid
#
# /etc/default/squid    Configuration settings for the Squid proxy
server.
#
 
# Max. number of filedescriptors to use. You can increase this on a busy
# cache to a maximum of (currently) 4096 filedescriptors. Default is
1024.
SQUID_MAXFD=4096


I can't realy find where could be the mistake.

L.G.

                                     ^^^^^^ I asked about memory because
of this line...

Two possibilities
1) The kernel is killing off squid because there's no VM left. What's in
/proc/meminfo ?
2) There's a process ulimit that squid hits and it gets killed off that
way. Check for ulimit
    in /etc/profile or the squid startup script

In either case, you need to lower the amount of memory used by squid to
below whatever the limit is.

I was hoping for some 'out of memory', or 'OOM killer', or 'zero order
allocation' errors in the dmesg output.
If they're not there then the second (ulimit) possibility is most
likely.
