SBS 2011 memory Issues server crawls to a halt
Posted on 2014-10-09
Recently one of our SBS 2011 servers (We are managing about 5 atm) has started to have some real issues with its memory usage and the server gets to a point where it grinds to a halt. At that point logging in VIA RDP and selecting restart can be a half an hour task.
One thing that is strange is the store.exe and w3wp.exe just continue to grow sometimes getting as big as 20,000,000K. This resets once the server is restarted.
During our monthly health checks we take note of memory at the time for things like this and for the past 3 years the store.exe was never recorded at more than 700,000K. (All of our other SBS servers are sitting around the same and have twice as many users as this one).
The server runs nothing out of the ordinary just the email & file services and has Sophos for AV and Shadow Protect for backup.
What seems to be happening is that every few days as the store.exe has grown up extremely high and the Shadow Protect runs its daily consolidation the server just locks up slows to a halt and has to be restarted.
Some of the server hardware specs. HP Proliant
Intel Xeon E5506
2x HDD in raid 5 for OS
2x HDD in raid 5 for Data and Exchange
Server is fully up to date and has had no hardware issue apart from 1 failed harddrive in the 3 years it has been running.
Searching myself a lot of the threads explain how Exchange 2010 and up allocate all of the spare memory and release it as needed.... I do not believe this is what is causing the issue. A lot of people also talk about limiting the amount that store.exe can allocate itself. While I am happy that changing that may fix this issue I am worried that overall there is some sort of memory issue that then may arise elsewhere.
Would love to get some thoughts?
