Re: [squid-users] Squid restarting

> What is said in your system messages log?
The messages from the OS are at the bottom, aren't very helpful though.
ulimit -a , and ulimit -aH don't show any limit at 256MB. But by watching the
mem usage through "mrtg", I could clearly see the graphics hitting a ceiling at
256. Then, using an equiv. of "top" ,I could predict a crash to happen in the
next few seconds.
It might be this :
(from http://www.ncsu.edu/itd/hpc/Documents/AIXMemoryModels.php)
"32-bit Memory Models : AIX divides memory into 256 MB segments.
The default memory model allocates a segment for kernel text and data associated
with the user process, a segment for user text, a segment for user stack and
data, a segment for shared library text, a segment for library data, and the
remaining segments are available to use as shared memory segments. Since user
stack and data share a 256 MB segment in this model, user data is restricted to
128 MB to allow room for the stack within the segment."

and More info there :

Well, I think I'll lower the value until I get to a stable situation.
128MB, then 64, etc ...
