Exchange 2013 CU1 MB Role - w3wp.exe memory usage

Exchange 2013 CU1 - w3wp.exe is consuming all the ram on MB servers which eventually causes DB's to failover to another server. Rebooting solves it but it's every 4-5 days now where this IIS process is sucking up all the ram. Anyone seen how to flush/fix this I dont have to keep moving the DB's and bouncing our MB servers? If it's an active sync user how do I locate? Thanks everyone.

Exchange 2013 CU3.

Since I believe this was fixed, even if you contacted MSFT they will advise you to update the system first and then monitor before they would provide this hotfix, which is most likely an interim update. If it is fixed in a later release, you will have to update to that latest release to obtain that IU.

This issue occurs because the MobileCapabilities object does not expire from the cahe as expected

Please refer the below my article.

I believe that issue (bug) was fixed in the newest release, which is Exchange 2013 RTM CU3.

Since there was a few bugs fixed within Exchange 2013 CU3 that occurred due to CU2, I would recommend upgrading directly to this patch revision on all Exchange 2013 servers within your organization.

Thanks!
