]My mail system is working so far as it should. Mail flow works, no claims from clients.
Anyway I've received the following warning:
- Back Pressure:
The resource pressure increased from Normal to Medium.
The following resources are under pressure:
Version buckets = 123 [Medium] [Normal=80 Medium=120 High=200]
Physical memory load = 97% [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\
) = 75% [Normal] [Normal=95% Medium=97% High=99%]
Queue database logging disk space ("C:\Program Files\Microsoft\Exchange Server\V14\TransportRoles\
\") = 75% [Normal] [Normal=93% Medium=95% High=97%]
Private bytes = 7% [Normal] [Normal=71% Medium=73% High=75%]
Batch Point = 0 [Normal] [Normal=2000 Medium=4000 High=8000]
Submission Queue = 0 [Normal] [Normal=1000 Medium=2000 High=4000]
I've found the following interesting article:
=> The Version buckets is not a problem so far
=> I'm bit in concern about the memory.
My system has the default roles installed -> MBX,HT,CAS and has 19GB of memory.
In the past I've extend the memory by adding + 7 GB. Now the errors cames again.
The store.exe consumes around 16 GB,
consumes around 1.8 gb
EdgeTransport.exe around 1.5 gb
The used physical memory is by around 98%
=> the stores.exe consumes a lot of memory - so it seems to be normal that you will reach the 94% of physical memory load.
(normal behavior i understand)
Is there a way to avoid this behavior or what we can do in this case?
A next step is to consider to create a new server and move the CAS and HUB role.
thanks and regards,
