We're not interested in omniNames are we?  I thought it was your
program which was hanging. From the trace it looks like omniNames is
working fine. The only slight concern is:

Which means "TCP connection was forcibly closed by remote host".
That's probably due to a client dying.

You need to run _your_ program with the tracing on, so we can see
what's happening to it.

Cheers,

Duncan.
