[Chilli] coova-chilli[14225]: net.c: 895: 11 (Resource temporarily unavailable)

[David Bird]

largelimits will probably not help. the resource temporarily unavailable
means it "would block" trying to write to the network -- likely because the
socket buffer is full.

However, the answer isn't to increase the socket buffer (the OS is already
not able to drain the buffer fast enough); adding to the buffer will just
increase the "bloat" ... it's better to just have the packet dropped (which
is what is happening).
