[cobalt-users] Server Load... Restart Services?

["Clint Decker" <nim1998@xxxxxxx>]

I got these 2 messages today in email.  (shown below)  And I guess its good
and bad... Its good because that means my sites are getting some good hits
recently... the bad thing... I guess the server cant handle it!

I hate hard rebooting the server from the admin area....  so does anyone
know how to restart like all the services in telnet, to get the same effect
as rebooting the raq?  Or is rebooting the raq like rebooting a PC....  When
you reboot a PC after it seems a little slower... its like your PC is brand
new again. Working perfect after the reboot.

I already rebooted the server, and the CPU load went WAY down.. but there
are still 101 processes and 99 sleeping.  Anyone know why?

Here is my top... I dont understand why I have sooooo many Processes and all
of them are sleeping.  As soon as I rebooted the server, I checked TOP again
and it still had a lot of processes...

  9:56am  up 9 min,  1 user,  load average: 0.90, 0.67, 0.35
116 processes: 113 sleeping, 2 running, 1 zombie, 0 stopped
CPU states:  4.4% user,  5.2% system,  0.0% nice, 90.2% idle
Mem:  128040K av, 125104K used,   2936K free, 208188K shrd,   2644K buff
Swap: 131536K av,   5912K used, 125624K free                 64976K cached

Subject: The CPU is heavily loaded

Over the past fifteen minutes, the CPU has been heavily loaded.
This will result in noticible performace loss. Consider moving some of the
services to other Cobalt servers, or reduce the complexity of the CGI
scripts running on the Cobalt server itself.
1 minute load average: 30.38
5 minute load average: 15.37
15 minute load average: 7.44

Subject: the SMTP (mail) server is not responding

The SMTP (mail) server appears to be down. The mail server may shut itself
down temporarily under extreme load, so you should also check the CPU load
on the server. If the load does not appear to be the problem, try turning
mail service off and then on within the Cobalt server Control Panel to see
if
this corrects the problem. If not, try rebooting the server itself. If this
still does not correct the problem, contact Cobalt Technical Support.
