The first comment while being way too harsh and a little unprofessional is typical of new Exchange admins. I run into this quite often as a consultant. Your article will be added to my "Knowledge Gems" folder to distribute to other newbie admins when this question comes up in the future. Thanks for taking the time to write this article. Keep up the good work. Jeff, for the record, I am no longer an Exchange admin - but have done it since the olden days.
Secondly, sorry you cried over my post. The concept of having a poorly behaving product is one thing, but to justify it's behaviour was a little over the top for me. To assume that Exchange is the only thing on that box is crazy. There could be other connectors - or what about backup software and a local tape drive.
Imagine the backup taking 10 hours because it can't get enough RAM to do it more efficiently? Sorry I offended. That's why it said: 1. In other words - we will decrease our store memory utilization as needed on the server too.
Hope that clears it up? Understood - and sorry to make a stir.. I'm one of those 'new' Exchange Admins. I've only been doing it for about three years. That's 'new', right? Well I actually DID encounter some problems with store.
Sure enough, Store. No, there were no performance problems unless you count the error and inability to send e-mails with any decent-sized attachment. Ok yeah, so there WERE performance problems.
Here comes my question Can I limit store. So - you can not set a cap limit on it. That was always the case for Exchange - even in 5. That being said - I would really suggest to open up a case with our support on this - if you are seeing memory errors. Basically depending on the memory pressure being put on the system and being sampled at a fairly aggressive rate , the store will release memory back to the system. Both spike memory usage at thier load time. You are commenting using your Google account.

It's this property that makes them popular in cache implementations. The cache developer assumes, correctly, that the cache data is released in the event of a potential memory shortage; in essence, to avoid an out-of-memory error in contrast to weak references , which never prevent the garbage collection of an object and would not be useful in a cache.
If improperly configured, the cache will grow until the available memory is exhausted, which causes the JVM to trigger a GC, clearing all soft references and removing their objects. Memory usage drops back to its base level, only to start growing again. The symptoms are easily mistaken for an incorrectly configured young generation and often trigger a GC tuning exercise. When an HTTP session is misused as a data cache, we refer to it as the session caching antipattern. This conversational state is found in most web applications dealing with nontrivial user interactions, but there are potential problems.
I've checked, and there are no backups running between 12PM and 6AM. From the statistics I have, this behaviour has been going for a while now at least 3 months but it's only for the past week that we've received alerts. So my question is: is there something that exchange server does during that time that's so memory hungry? I don't believe that to be the case and I've never seen documentation or anecdotal evidence to suggest such behavior.
Database maintenance occurs by default between 1AM and 5AM. That would be my guess as to what's causing the spike. Sign up to join this community. The best answers are voted up and rise to the top.
