I have recently installed exchange 2007 server in co-existance with exchange 2003. The process edgetransport.exe on the exchange 2007 consumes more than 5GB of memory and causes the routing group connector between the exchange 2003 and exchange 2007 servers to stop working. All internal and external email queue in the routing group connector on the exchange 2003 server. All user mailboxes reside on the exchange 2007 server, as a result no emails are sent or received by users.
I receive the following error in the event log of the exchange 2007 server:
Resource pressure increased from Normal to Medium:
Resource utilization of the following resources exceeded the normal level private bytes = 73% (medium)...
Back pressure caused the following components to be disabled:
Inbound mail submission fron the internet
Mail submission from the pickup directory
Mail submission from the replay directory
Loading of email from the queuing database
