The Windows unit test cycle that built m-c revision 3fd33e46a2cd (Mon Mar 23 10:46:41 2009 -0700) went orange with these errors:

make: *** [mochitest-chrome] Error 1
Unknown Error: command finished with exit code: 2

The next cycle went green with no changes to relevant code.  So this was a pure machine load issue, as far as I can see.

Oh, the relevant logs:

This build ran on moz2-win32-slave10, which was migrated from one ESX host to another at 13:10 PDT (bm-vmware03 to 06). That was 40 minutes into the mochitest-plain run but 25 minutes before it gave up, so I don't think it was the short pause for the migration causing the problem. Load on the destination host looks OK, but the data is fairly low resolution. We need to catch one of these in the act to figure out what's happening.

Nick - are you watching for this issue?  Would it be appropriate to assign the bug to you?

As far as I can see this error hasn't repeated, and timeouts on win/linux are occuring at much the same rate as on Mac.
