Sorry, I am currently traveling. Away from real computer until April 7th.

Those buildbots are hosted in OpenIndiana infraestructure. I take care
of the Solaris Zone (similar to docker but better :-)) but I can't
interact with the "real" machine. Sometimes changes in the "real"
machine had impacted us and nobody realized until some time later, when
nobody remembers what was changed or who did it.

I have contacted the machine manager and he has said to me that 16GB
were taken in the "/tmp" directory by buildbot user. He has deleted them
and everything should be fine now. Lets see.

Anyway if buildbot is leaving garbage behind we should take care of it.
Doing a daily cron for manual cleaning up seems a bit hacky :).

I would be interested, too, in getting an email when one of my buildbots
is red for more than, lets say, 4 days in a row. An email per day would
be fine.

BTW, buildbot pages are painfully slow. The manager had to "insist" and
be patient to see
<http://buildbot.python.org/all/waterfall?show=x86%20OpenIndiana%203.x>,
etc.

How can that be improved?.

Thanks for keeping me in the loop. I hope everything is going green for
a while now :)
