I'm running a snapshot from 2015-06-26 (a little over a month old at this point) and the chatbot seems to be leaking memory rather quickly. A few snapshots from various points in time:
3:09pm:
PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND
19511 swills 1 35 15 3030M 2216M select 2 2:24 0.00% php ./exec_daemon.php PhabricatorBot
3:14pm:

3:50pm:
PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND
19511 swills 1 35 15 3190M 2336M select 6 2:37 0.38% php ./exec_daemon.php PhabricatorBot
I can restart it regularly of course, but that clutters up the channel with join/part messages and at the rate it's leaking, I'm going to have to restart it fairly often.
