RSF14004: Heap memory exhausted while client of backend server '%1' in backend farm '%2' is '%3'

Error code	14004
Error constant	RSF_CLIENT_OUT_OF_MEM
Parameter 1	Backend server name
Parameter 2	Backend farm name
Parameter 3	Internal context

Probable cause

The client request was aborted but the backend server should remain usable for other clients. The low memory situation may be caused by temporary high traffic volume. If this error persists on an IIS based Relay Server, please check if the application pool setting is limiting memory usage of your Relay Server web server extensions. Increasing the maximum number of worker processes in the application pool on a 32-bit IIS will help spread the load. Upgrading to a 64-bit Relay Server or adding Relay Servers to the Relay Server farm can also be valid solutions. Offloading other applications running on the Relay Server machine to other machines may also help.
