Hi All,

We're seeing a slightly strange (we think) issue on some production
servers. While most of the servers seem to hover around 20 to 250
Active Connections, according to instrumentation under PerfMon (UPM:
Active Connection Count) we have a couple of servers which are showing
rather more. In the order of 42000000000 connections in fact (rounded).
Has anyone seen anything like this before?

Also, does anyone have any sample data they'd be willing to share? What
sort of active connection counts do you see on your production servers?
No details other than a number needed, purely anonymous!

Thanks for anyone taking the trouble to reply,

Andrew Cherry

Andrew,

The number of active connections will depend largely on how much traffic
your site receives, how many servers are in your web farm, etc. It's
different from environment to environment, but 20 to 250 active connections
seems like a reasonable number.

I'm going to go out on a limb and say that 42 billion active connections
appearing in this panel is probably a bug. I haven't seen this one
personally, but it wouldn't be the first time that perfmon counters were
rendering incorrectly. Does this happen on seemingly random machines at any
given time, or are you seeing these metrics on specific boxes? This sort of
thing might be an unexpected side effect from a hotfix that has only been
applied on a specifc server. In any case, you could probably open up a
ticket with Microsoft Support to correct this issue.
