. . .

I can't really help with your other problems, but:
no, on a 2GHz machine 1000 is a fine value for
that.

In case you were curious, it can be set at boot-time
via a "kern.hz=" line in your /boot/loader.conf.

Thank you for your reply, we actually initialized over 1200 python
threads on each server. I'll try to low down the thread number for
tracking the problem.

Look at the number of processes you've got-- most likely you've got  
some scripts leaving zombie processes around, or one of the server  
programs you are running isn't cleaning up after it's children  
properly.  Do a "ps aux" and look for excessive numbers of processes

It's top shows wrong load percent?

2007-08-22 Thread Nguyen Tam Chinh 
Hello,

Recently we got some trouble on some FreeBSD 6.2-STABLE servers
(GENERIC kernel). Some python scripts are working on these servers and
after a day or two we get 0% idle in the CPU states. After sometime,
the operating system will unable to do even simple task like resolving
DNS name and the zabbix process can not send outbound packets to the
remote monitoring server. Maybe the top is showing wrong load percent?
vmstat -i shows that some kind of irq0: clk has a maximum value of
1000. Does this matter?
Please advice how to debug this overload problem.
Thank you very much!
