Subject Re: [users@httpd] False "Out of Memory" errors - on new Suse Linux SLES 9.1 - Apache 2.0.54 - Blade servers running 4 GB of RAM

Thanks Kieth, well I learned something new, but no I do not have the 
parameter set anywhere in my conf. So MaxMemFree should be unlimited, 
right ?

Is this of any relevance Jignesh?


MaxMemFree Directive

Description:
Maximum amount of memory that the main allocator is allowed 
to hold without calling free()

Syntax:
MaxMemFree KBytes

Default:
MaxMemFree 0

Context:
server config

Status:
MPM

Module:
beos, leader, mpm_netware, prefork, threadpool, worker, 
mpm_winnt

The MaxMemFree directive sets the maximum number of free 
Kbytes that the main allocator is allowed to hold without 
calling free(). When not set, or when set to zero, the 
threshold will be set to unlimited.

In theory, theory and practice are the same;
In practice they are not.
