I get the following messages in my syslog at regular intervals:

Restart of ypbind and portmap doesn't help. My /etc/yp.conf is empty
(no lines without # first) and nis seems to work.

Any suggestions?

A very similar bug was filed on alpha which appears to be a problem in
glibc - it's http://bugs.debian.org/231593 - this sounds like the same
thing.

Could you please generate a strace of ypbind when it's doing this (you
can use the '-p' option to attach to a running process) and send the
results to the bug log?

Thanks.

OK attached is an strace, I hope it helps!

I also tested this:

And when I tried this:

sid:~# ypcat passwd
YPBINDPROC_DOMAIN: Domain not bound
No such map passwd.byname. Reason: Can't bind to server which serves this domain
sid:~#

In other words: ypbind don't work at all when -broadcast -debug is
passed as arguments.

I also tried ltrace, but then ypbind crashed. This might be a problem
with ltrace on amd64.

Interesting...  Is the trace you sent definately for a failing ypbind?

Yes, you can easily find all error messages to syslog by searching for
ypbind in the trace.
