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.
