----------------------------------------
[~dtw] thanks, that was enough information to debug:

The tracking logic is incorrectly dealing with non-scalar resources. It's not
supposed to insert empty entries when tracking, or expect empty entries when
untracking an empty amount, but it does both.

> We recently upgraded our Mesos cluster from version 1.3 to 1.5, and since
> then have been getting periodic master crashes due to this error:

> Full stack trace is at the end of this issue description. When the master
> fails, we automatically restart it and it rejoins the cluster just fine. I
> did some initial searching and was unable to find any existing bug reports or
> other people experiencing this issue. We run a cluster of 3 masters, and see
> crashes on all 3 instances.
> Right before the crash, we saw a {{Removed agent:...}} log line noting that
> it was agent 9b912afa-1ced-49db-9c85-7bc5a22ef072-S6 that was removed.
