What happens is in nailgun logs there are many instances of:
Tue Nov 4 16:34:16 2014 - *** uWSGI listen queue of socket ":8001" (fd: 3) full !!! (100/100) ***
Raising uWSGI listeners and # of listen sockets should reduce this problem.

Raise number of nailgun uWSGI workers and sockets
Fixes issue where nailgun stops responding to requests
because all workers are occupied and the queue of
available uWSGI sockets fills up by increasing the
number of workers (double) and raising the connection
limit from 100 to 4096.
