Re: [Xen-users] Domain 0 reboot when network flow is heavy

[Xin Chen <xcheney@xxxxxxxxxxxxxx>]

Thanks Tom,

I did these experiments on domain 0 today:
First, I shutdown the guest systems running on domain 0, in case domain 
0 reboots.
1, write a script:
!#/bin/sh
while [ 1 ] do
/proc/slabinfo >> ./slabinfo.txt
end

then keep this script running around 20 mins, until slabinfo.txt about 
4gb, domain 0 still running ok.
2, choose a 10gb file called temp, and do scp
#scp temp localhost:/tmp/temp
copying speed: 25mb/s, domain 0 still running ok.

3, again, like yesterday, scp a large file from remote server to domain 
0.   I did it twice, and domain 0 still running ok.
I am not sure what it tells, I need to test again. Just may give a idea 
that it only happens when there is a guest running???
xin
