Hi all!
I wrote to the list a little while ago, about a problem in 2.1.129
which caused the kernel to (at least seem to) take up very high system
load for no reason what so ever.
Well, the problem returned. Output from top:

I can assure you, that top does NOT take 60% CPU time on a PPro150 usually !
This happens approx. once a day, when the machine has been under fairly heavy
load for some time (just load 5-7, nothing dramatic). It does not seem to
have anything to do with heavy swapping, as I presumed in my first post.
The fun thing is, that if I stop the two rc5des clients so the CPUs get a
little idle-time, the problem vanishes.
When I start the rc5 clients again, everything is normal, at least until I
start to load the system heavily agagin, which is when the problem re-appears.
This is the top after I re-started the rc5 clients:
10:08pm up 1 day, 21:34, 9 users, load average: 2.61, 3.26, 3.61

I never saw this under 2.1.125 or .126, but have seen it both in 129 and 130.
Is there _anything_ I can do to help track this down ?
