Store.exe not releasing memory?
Posted on 2014-04-27
We are running SBS 2011 with Exchange 2010 on a server with 16G of memory. Recently there are have been issues with remote logins via RWW. Users can connect to the sharepoint site but when they try to continue on to make a connection to one of the remote machines nothing happens.
While troubleshooting I am finding that memory usage is at or close to 100% with store.exe using most of the available memory (about 8.5G). If I stop then restart the service the store.exe memory usage drops way down to a reasonable level and users are then able to connect remotely without difficultly. Memory usage will then remain stable for 5 or 6 hours but eventually when I check back store.exe has again sucked up all the memory and users cannont connect.
I know that many say that it is normal for store.exe to use all available memory but I do not see this behavior on two other SBS machine I manage. At the very least it would appear to me that store.exe is not releasing memory back to the pool when it is needed. I also don't see why it would be necessary for store.exe to use 8.5G of memory to support email for 12 users when no one is in the office.
The remote connection issue started to appear within the last couple of weeks. This would coincide with some updates that were installed at or around that time (Exchange Rollup 8 - 4/14 and Sharepoint SP2 with a couple of other Sharepoint updates on 4/18).
I am considering rolling back the updates but am concerned about compounding problems. Any thoughts or troubleshooting tips would be appreciated.
