Microarmy bails out with 380 instances.

[coredump]

Tried to use 380 and 200 instances for a big test, microarmy just stopped during the deploy phase. Instances where created but the command never returned. Manually added the microarmy tag to the created instances and used 'find_cannons', worked. Tried 'deploy' but after a long time got a long list of EOF exception (all the same traceback)

Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/eventlet/hubs/hub.py", line 336, in fire_timers

Fascinating. I have never tried this on so many instances!

Any idea what the system resources were like on your side?

I might have to try turning on this many computers for a conclusive answer... :D

I didn't really measure it but I didn't notice anything going wrong on my side.
