Exchange 2010 - MSExchangeISClient\Client Connection count is over 2 billion - yes 2 billion
Posted on 2010-09-20
Trying to troubleshoot a performance issue here. Here is what I got;
Separate servers for each role (cas, hub, mailbox)
80 users, all running in cached exchange mode
all users have blackberries
In troubleshooting, I noticed something, on my Mailbox server, the MSExchangeISClient\Client Connection count is over 2 billion. You read that right. Almost all of it is from the Exchange Administrator account.
Now I have another location in my active directory set the same way as this location, their client connection count peaks around 800. They have around 35 users.
What is causing all these client connects on that one server to reach over 2 billion? and from the ex admin account? I don't get it. How do I narrow this down?
Each exchange server has 8GB of ram, 2 procs, pretty heavy machines. - not sure how much that matters, given the information at hand.
