More possibly it's caused by remote system load (or link congestion
or whatever other reason for remote system not able to receive updates
fast enough). Then, when socket buffer is full with unacknowledged data,
your system tries to send another update/keepalive message and it 
results in write(2) syscall returning EAGAIN error (actually, not
an error, just and indication of 'no data sent, try again later'),
which translates to "Resource temporarily unavailable" message.
