Frequent crashes on 4.9STABLE

[Ajit Anand]

Hi ,

Thanks for your reply.  I am forwarding the information which you require

Apache Version 	: Apache/1.3.29
PHP         	: 4.3.4
Perl   		: 5.005_03
MySQL 		: 4.0.15

memtest (/usr/ports/sysutils/memtest) runs without any problems

I have attached the process list and the kernel configuration.  We are 
using the 4.9RELEASE and have not cvsup'd the source after installation.

Regards

Ajit
