next in thread | raw e-mail | index | archive | help
hi list,
my server is frequently shutted down by itself. I've checked all of relevant logs, but it showed nothing suspicious. Then, I realized from the output of ps -aux that [swi1: net], and some irq have consumed the cpu load.
# ps aux |more
USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND
root 10 42.7 0.0 0 8 ?? RL 6:26PM 26:46.85 [idle]
root 31 21.7 0.0 0 8 ?? WL 6:26PM 7:24.36 [irq18: rl0]
root 11 20.3 0.0 0 8 ?? WL 6:26PM 24:59.95 [swi1: net]
root 32 6.2 0.0 0 8 ?? WL 6:26PM 9:15.25 [irq19: rl1]
....
that was in "good" condition. usually, [swi1: net] consumed up >70% of cpu load, then followed by irq process on rl1 and rl0 interfaces.
I've read through swi manual, and knows that this function is used to register and schedule software interrupt handlers. but I don't know what exactly "net" has made the interrupt.
my question :
- why did the swi process eat up my cpu load? what is the cause?
- is the rl0 and rl1 has some problems, so their irq process consume some cpu load?
- is there any relation between these problems with my server's self-shutted-down-behavior?
thanks a lot for your responses.
