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.

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!
