[Xen-users] domU btdownload problems

[Sipos Ferenc <frank@xxxxxxx>]

Hi Guys.

When I'm running a python based bittorrent client in one of my DomUs
after having it run for a couple of minutes the whole networking dies.
Here is all I get. Is it related to the fact that my domU has 'only'
128MByte physical RAM assigned to and when a burst of network packets
come thru bittorrent it runs out of memory? What shall I do to prevent this?

Thanks,
Frank
