Thanks Tommy.

On the one hand, let's resolve the ambiguity about why your server is
overflowing a buffer on messaging.  If we knew the exact line of code
that was failing we could pinpoint it accurately.  But to do you must
attach gdb to ntserv just before it fails, then capture a backtrace.

	% gdb -p $(pgrep ntserv) lib/ntserv
	(gdb) continue
	(gdb) bt

On the other hand, the latest source doesn't have the problem; tested
Ubuntu 14.04 LTS.  The fix was already applied.  In doing the above
we'd only learn exactly how old your source was.

I've tried looking for the fix, but there are so many, and I don't
know which version of the server you are using.

Your quickest fix should be to use the latest source, which I've
tested repeatedly and does not do for me what you observe.

Please clone from git, run, then follow INSTALL.

	git clone
	cd netrek-server

My best guess is that you followed to which had said the latest release
of the server was 2.14 from 2008.  That directory was out of date, and
I've fixed it now.  Latest is 2.18 from 2011, but the latest source in
git is the best. was up to date.
