Could someone cast an eye over this please - eventually swap fills and
the server dies. Its under very light load, a few php sites, some direct
html pages, some perl and java.
First the system spec:
[EMAIL PROTECTED] conf]# uname -r
2.6.17-1.2142_FC4smp
[EMAIL PROTECTED] conf]# httpd -version
Server version: Apache/2.0.54
Server built: Jul 26 2006 11:00:19
Check memory:
[EMAIL PROTECTED] conf]# free -m
total used free shared buffers cached
Mem: 740 732 8 0 6 102
-/+ buffers/cache: 623 117
Swap: 1027 479 548
Ugh! Swapping already...I know how to fix it though, but before I do
does this look normal?
[EMAIL PROTECTED] conf]# ps aux | grep httpd

httpd is taking 53% of RAM Alright lets free some up:
[EMAIL PROTECTED] conf]# service httpd restart
Stopping httpd: [ OK ]
Starting httpd: [ OK ]
Check again:
[EMAIL PROTECTED] conf]# free -m
total used free shared buffers cached
Mem: 740 409 330 0 7 110
-/+ buffers/cache: 292 448
Swap: 1027 280 747
Bingo! Restarting httpd had a big effect on swap. I would love to know
exactly what those httpd children were doing - is there an easy way to
tell please?
Thanks
