Problems under vmware ESXi

D

Dara

Hi, i am having some problems with a freebsd server guest under vmware ESXi and was hoping for some help.

The problem is that the systems is slow and seems to freeze every other minute or so for a second or two and a cant find any errors, so if anybody have any tips/tricks for finding whats wrong that would be great..

Info:
FreeBSD kalle.hobbe.something 7.0-RELEASE FreeBSD 7.0-RELEASE #0: Wed Oct 29 14:35:04 CET 2008 drift@kalle.hobbe.something:/usr/obj/usr/src/sys/KALLE amd64

I have recompiled the kernel to get ULE, and i have tried putting kern.hz=100 in /boot/loader.conf.

I got nothing in the logs

If i cant solve this i have to try to move everything to fbsd 7.1 and see if that solves the problem but there is allot of websites so i rather not..

Anything that looks strange ?
 
In the future use [ code ] tag for commands output.

Stats look good, do these freezes occure with high network load? If yes you may also try using software interupts for your FreeBSD network interface using poilling(4).

example configuration @ /etc/rc.conf
Code: 
-ifconfig_em0="DHCP"
+ifconfig_em0="DHCP polling"
You will also propably have to recompile kernel with device polling.

But I am not sure if it will really help here, what about your ESX load btw?
 
Ok, i will try that. The load isent high at all so its a little bit weird.. i have bean running allot of FreeBSD on ESXi for a while now but never seen this before, but its a first time for everything so.
