Re: [Xen-users] Memory squeeze in netback driver

[Aaron Stewart <aaron@xxxxxxxxxxxxxx>]

Yep, just started seeing this ourselves today.    In our case we have 12 
domU's running on one server with 4gig (see config below)
A reboot of the dom0 solved the problem, but i'd like to keep it from 
recurring.  Anyone have any clue what's occurring? 

Our config:

Dell PowerEdge 850, Pentium D 930, 3ghz, CentOS 4.3
Running para-virtualized (Intel VT is on, but we are not currently 
running in hvm mode on this system).
Kernel: 2.6.16-xen3_86.1_rhel4.1 (stock from xensource)

We have well over 30 systems that have run this config for several 
months, and this is the first time I've seen this.
Any thoughts?
