Every so often I get the following event in the Application Log on our Exchange 2010 SP1 server.
The resource pressure increased from Normal to Medium.
The following resources are under pressure:
Version buckets = 120 [Medium] [Normal=80 Medium=120 High=200]
Physical memory load = 94% [limit is 94% to start dehydrating messages.]
The following components are disabled due to back pressure:
Inbound mail submission from the Internet
Mail submission from Pickup directory
Mail submission from Replay directory
Mail delivery to remote domains
The following resources are in normal state:
Queue database and disk space ("C:\Program Files\Microsoft\Exchange Server\V14\TransportRoles\data\Queue\mail.que") = 67% [Normal] [Normal=94% Medium=96% High=98%]
Queue database logging disk space ("C:\Program Files\Microsoft\Exchange Server\V14\TransportRoles\data\Queue\") = 68% [Normal] [Normal=92% Medium=94% High=96%]
Private bytes = 5% [Normal] [Normal=71% Medium=73% High=75%]
Batch Point = 0 [Normal] [Normal=1000 Medium=2000 High=4000]
Submission Queue = 0 [Normal] [Normal=1000 Medium=2000 High=4000]
Any ideas on how to stop this from stopping mail flow?
