I have an Exchange server 2013, over the weekend I have installed Cumulative Update 6. After the installation I have noticed that the CPU is stuck at 100%. When I have checked the processes there is a process noderunner.exe using large amounts of memory and CPU.

I am also experiencing intermittent connection to the Exchange server from Outlook. I do not know if this is related to the high CPU usage but if anyone has any ideas on how to troubleshoot and find a solution I appreciate your help.

How long has this server been up and running prior to CU6?

What are the server specs?

How many mailboxes?

The server has was installed earlier this year. It has been active about 6 months.
We have about 400 user mailboxes and about 150 DL mailboxes.
It is 32GB, and an Intel Xenon 2,27GHz

all exchange version starting from 2007, uses high IOPs and this led to many organizations to go with Virtual setups.

If you do not have budget constrains I would suggest you to start with VMware. Less head aches and easy management.

Turns out the problem was related to updating Exchange 2013 to CU6. I worked with Microsoft Exchange Support to install an update they provided to fix the problem.

Thanks everyone for your comments.
