I have Cent OS 5.1
I also have http://phpsysinfo.sourceforge.net/
I have asterisk running .
Now when I look at System Information ,
I see that "Physical Memory" keep increasing and at one point it reaches 96%. Then my sever get hang and then I have to restart it.
I have 4 GB RAM.
Processors 2 Model Intel(R) Core(TM)2 Duo CPU E7200 @ 2.53GHz CPU Speed 2.53 GHz Cache Size 3.00 MB System Bogomips 10135.71
Kernel Version 2.6.18-53.el5 (SMP) Distro Name CentOS release 5 (Final) Load Averages 0.27 0.35 0.31
What could be the reason ?
ps ax shows :
