There is nothing untoward in any log as far as I can see. The oom killer hasn't come out to play either.

Anyway, xenbits is now running 0.8.1, I'll upgrade as Bryan suggests once a new version is called.

We've had 0.8.1 testing on an internal server for a few days so I have confidence the upgrade should be safe. As ever, do let me know if any problems are seen.

Note that the temporary server that the 3.0-testing tree is redirected to is still running 0.7 but will disappear shortly once I move the hosting to our new colo centre.

Could you check the xenbits server logs to see if there are hg processes

It may also be worth upgrading the server to the current tip version of
Mercurial, once that has seen some more testing.  Matt just merged some
changes written by Chris Mason that reduce disk and memory usage
substantially, which should reduce the squeeze that the xenbits server
gets put under.

I'll see what we can do to print a more useful error message when the
xenbits server gets killed, as it's quite a common problem.
