SUMMARY: Sendmail/NIS hang on Unknown User

I eventually tracked this down to a sendmail/NIS interaction, by running
trace on the sendmail processes.

My co-worker had put some line such as:
Dummy:*:::PhD Students::
into the NIS password file.

While Sendmail was reading the NIS password database it hung, complaining
of a lack of bufferspace and logging 'sendmail: [1310] :locked' to syslog.

The solution is to remove the 'Dummy' lines from the NIS password file, and
all is well again.

Dummy sums it up really.
