Sounds like something is connecting to the listener socket a lot and
then not doing a proper disconnect, then connecting again.  Could
also be someone doing port scanning on your box.

Any process with "defunct" listed means that the process has died
but it's parent process has not reaped the process status yet.
Sometimes if it has been orphanes you have to wait for the "init"
process to come along and do that.

If Xastir detects that one of the forked processes has died it tries
to do a "wait" in order to reap the process.

Assuming it isn't something peculiar about your system that is doing
it, one thing that usually works well is to set the KEEPALIVE flag
so that Xastir tries to send some out-of-band data periodically just
to keep a stream alive.  If a connection doesn't go end-to-end,
Xastir will detect it at that point.
