[users at bb.net] buildbot CPU usage

Tue Aug 2 14:12:41 UTC 2016

Sometimes it goes up to 140%. I was not able to relate this with a
particular builds condition - seems like it can happen any time and is not
related to how many builds are going on.

I usually realize the server got into this state because the web UI gets
stuck. As soon as the CPU% goes back to normal values (2-3% most times) the
web finishes loading just instantly.

Any pointers as to what might be causing this? Only reason I can think of
is too many people trying to access the web UI simultaniously - may I be
right?
