Mike:
You might look for things like SQL Server, Anti-Virus, and other
software that does things every day. I've run into installations
where SQL Server was installed as some kind of administration tool.
Something fired off every hour in SQL Server which brought to (almost)
a complete halt telnet responsiveness for several minutes. Once this
was identified, I had to identify this since the administrator
couldn't, and put off then responsiveness was very acceptable.
Windows is very tricky when the dbms is loaded onto a multi-use server
(I'm sure the same is true in Linux/Unix).
HTH,
Bill

We are running UniVerse on Windows 2003 Server in a virtualized environment.
99% of the time the system runs great and we have no issues, however, about
once a day or every other day during the busiest time, we have a period of
2-3 minutes where the server slows down and basically quits responding.
Without us taking any action the system begins responding normally again
and we usually make it through that day without issue.
We typically have around 85 users on the system at one time sometimes that
gets up closer to 95 or 100 but not often. I have noticed certain processes
that definitely cause the issue like running winmsd from the command line or
renaming a directory on the server. Since I know these processes cause the
issue I don't do that during the day. Obviously there are other processes
that also can cause issues for us.
We have worked with our vendor and Rocket and the latest we've gotten from
them is that our server is under-resourced. While that very well could be
true, we want to do a little more research first and reach out to other
Windows/UniVerse users to see what hardware they are running and if anyone
is in a virtualized environment.
Any help we can get would be appreciated.
Thanks
Mike Roosa
