Status: RESOLVED WORKSFORME

Description

We hit this repeatedly during l10n repacks for 3.5.12. During get_enUS_src, we saw:

This was compounded (as usual) by the bad slave failing early and returning to the pool to accept more jobs (and fail again).

Could just be a bad slave, but it should be audited and/or re-imaged.

I've renamed buildbot.tac -> buildbot.tac.off for now.

Hasn't been a recent recurrence that I can see, and this slave is up-to-date with OPSI.
