slave registering itself multiple times

[Scott Smith <sc...@gmail.com>]

Running mesos #1205738 (should I upgrade? if so, will it still work
with the git head of Spark?)

I find often mesos-slave's are getting registered multiple times:

I know for a fact mesos-slave is only being run once; I added a 'date
>> file' line to the script that launches it and checked the file.  It
doesn't matter if I add a sleep, nohup, and/or stdin/out/err
redirections.

I have attached the tcpdump from that session.
