Does this always show up at around the same time? Any idea why someone's
tokens are expiring / how long are these compile jobs running for?

One thing that's easy to try is to disable the fileserver abort
throttling by passing '-abortthreshold 0' in the fileserver arguments,
as that can affect behavior like this. We don't really offer any good
way to detect if that's the actual problem, but just trying to disable
them is easy to do. It does require restarting the fileserver, though.

Or, well... it may be detectable if you are willing to share with me a
core of the fileserver captured while this is happening, but even then
iirc it may annoying to go through.
