You're definitely not at Hobbit's maximum as this user has twice the number
of hosts!

Just a thought ....

Once I start to get around 2700 hosts hobbit stops updating. Is there a
cause for this in hobbit (memory or host limit)? Top shows my system with
very little utilization of memory or cpu and all hosts go purple for no
updates.  I can get hobbit updating again by commenting out hosts and
restarting it but I still have roughly another fifteen hundred hosts to
enter.
I have been adding the hosts in slowly in groups of less than two hundred
which seems to work better as I was seeing everything go purple at under two
thousand hosts before.
