I can check for this wait a sec and retry the connect but I don't think
that will cure the problem. You will have to figure out what its
running out of -- most likely thing is sockets.
hmmm.... that is presumably EAGAIN, linux connect man page says:
EAGAIN No more free local ports or insufficient entries in the routing
cache. For PF_INET see the net.ipv4.ip_local_port_range sysctl
in ip(7) on how to increase the number of local ports.

On linux I've run it with -p 100 without problems.
