Though I don't know the syntax for setting the parameters on Linux, 
you should look into increasing the number of pending connections
for your tcp listener.  There should also be a corresponding number
of incomplete pending connections.  I was having some RPC connections
failing on my solaris system.  Default for was 128.  For reference - here
is how I increased these params in Solaris

ndd -set /dev/tcp tcp_conn_req_max_q 1024
ndd -set /dev/tcp tcp_conn_req_max_q0 2048

Hope this helps
