I have about 40 Apollo 3000 and 3500 machines running DOMAIN/OS 10.2.  I'm
currently running ntp version 1 on the machines and they are keeping time quite
well.  However, I would like to upgrade the software to the xntp package kept
on louie.udel.edu so that I can run the same software on those machines and
the rest of the machines in our department.

I would like to know if anyone has done this and experimented with values for
the variables tickadj and tick.  DOMAIN/OS doesn't have kmem or libkvm, so I
defined NOKMEM and used the default values.  However, on the one machine that
I am testing the software on, the hourly log information displays increasingly
larger values for freq, until it finally dies with the message

Drift exceeds +371ppm, cannot cope.

I don't know that much about the code, so perhaps I'm off track believing that
this error results from poor values for tickadj and tick.

Someone running the version 2 xntp package had some patches for DOMAIN/OS
however I don't have them.  I'm willing to try them out if someone will send
them to me and I'll post my results.
