Thinking that maybe we were just running near the edge on resource limits, I resized the droplet from 2GB to 4GB RAM.  When buildbot starts, the python process uses about 80MB.  But it seems to grow fairly rapidly.  Here is the output from top after a few hours:

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND   931 buildbot  20   0 3141096   3.0g   9780 R 103.0  76.4 111:40.02 python3

So it seems something is wrong there.  I don't think the buildbot server process should need that much memory and I don't recall this being a problem previously.

I updated to a newer version.   We were using 2.7.0-1, now we have 2.8.2-3.  I'll watch and see if that improves things.

Hmm, seems to be doing the same thing again after 90 minutes or so we are up to

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1148 buildbot 20 0 3142408 3.0g 9636 S 75.0 76.5 56:44.73 python3

I have no idea why this is happening. Is it buildbot? Python 3? Something wrong with our configuration?
