A possible cause could be blocking dns lookups.


When you see the queues fill up again try to attach with gdb to the
corresponding ser process (gdb ser pid).  You can see the pid using
netstat -anp. Send me the output of the bt (gdb command). It should tell
what that ser process is doing.

Also for debugging run it with very few children (2, 3). If it's
something that blocks the processes, this should make it happen faster
