Re: [Xen-users] DomU hangs sporadically
Thanks for the response Phil, It was my understanding that redhat backported all current fixes to the current build and just left the 3.0.3 as the "current" build. My current hardware architecture is rather "old" IBM xseries servers (8 cpu Xeons 16GB of RAM, 2 Dual port Gigabit NICs).
I'll try that "fix" but that is only for the Dom0 domain not the DomU. It was my belief that I am routing all my xen traffic out the different network ports instead of one central port. Would this "fix" then have to be applied across each DomU?
Would upgrading to 3.2 work any differently? Are they any fixes or patches in there that would solve this problem? I'm still pegging it on the driver in Xen for my network cards, still can't seem to understand how it deals with the drivers.

Hi Jonathan
The system you're running may be too new to be suffering from this MTU related
problem, but it might be worth reading this posting:
