Have a problem with kernel errors on a debian lenny xen system.
Both Dom0 and domu have 2.6.26-2-xen-686 kernel
it's a Dell Poweredge 1600sc.
Dom0 and another domu have no errors
It can run fine for days and at some point will get messages like this about
ever 2 minutes.

[99893.452938] =======================
Load is 1 but looks idle.
top - 15:52:11 up 1 day, 3:55, 1 user, load average: 1.00, 1.00, 1.00
Tasks: 124 total, 1 running, 122 sleeping, 0 stopped, 1 zombie
Cpu(s): 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st
Mem: 2097348k total, 1212396k used, 884952k free, 9596k buffers
Swap: 2097144k total, 0k used, 2097144k free, 649000k cached
The only way I have been able to get the load back down is to reboot the domu.
I thought I had it licked as it has sometime worked for over 5 days with no
errors so I have installed it in a remote office so at this point rather not
do any major changes.
Any Ideas?
John
