Hi,
yesterday i have noticed that my cpu is runnig on 100%.
And almost 100% is used on interrupts
CPU states: 0.0% user, 0.0% nice, 1.4% system, 98.6% interrupt, 0.0% idle
i tried to check what is going on.
I ran top and pressed S so i could see all processes:
PID USERNAME THR PRI NICE SIZE RES STATE TIME WCPU COMMAND
27 root 1 -32 -151 0K 8K RUN 62:48 67.72% swi4: clock
29 root 1 -44 -163 0K 8K RUN 28:30 28.17% swi1: net
11 root 1 171 52 0K 8K RUN 1:03 1.12% idle
I have noticed that clock is eating most free cpu time.
Net load is in normal because this is router for about 150 hosts.
Could any one tell me what is going on?
I am running FreeBSD 6.0-STABLE. i didnt have any problems like that before
with FreeBSD 6.0-BETA ,RC,RELEASE and even STABLE. This happend
yesterday or dwo days ago. I have downloaded newest src from cvsup and
recompiled kernel which took quite long time due cpu usage.
System is runnig postfix,mysql,apache2,dhcpd.
I have attached my kernel config.
I dont know where to look for problem. Please help me with this.
