Store.exe allocating memory, & slow Internet - think it is a SQL server issue!

I keep getting a performance alert telling me that I need to watch the RAM used by Store.exe.  I know this is to do with exchange Information store and that I need to restart it.  This I have done, however I get the error again around 5 days later.  The other thing that happens at the same time is that because we are running premium edition it seems to slow down the internet to a halt. (Running ISA 2000 in cache mode only)

FYI our server has 1 NIC and DOES NOT use the built-in firewall function.  We simply go trhough a router.

I have tried removing the proxy settings from the client on the internet side of thing but this makes no differnce. I have to restart the information store to solve it. I have not solved the slow internet yet though!

Please help

Well, adding a second NIC would be the logical thing to do... considering you aren't really getting ANY benifit by caching alone.

It sounds as though you might not have installed SP1 yet?  If you haven't... you should.  It resolves a lot of performance issues.

Then, take a look at these articles regarding allocated memory alerts on SBS:

Hum! You are describing a lot of traffic on the network when the store incident occur. But that could also be false.

This is what I would Check:
1.- Check if your exchange server is not acting as an open relay.

2.- Make sure the nic card is ok or the correct driver is installed

3.-Check the following link: http://support.microsoft.com/kb/867628

Good luck!

I was going to mention KB 867628 as well... the alert you are getting can generally be ignored.  The Exchange store will take up whatever RAM it can, but it easily gives it up when requested, so it's not a real problem in most cases.  What you generally need to watch is your SQL Server instances, which CAN be an issue.

See http://msmvps.com/blogs/bradley/archive/2005/02/04/34984.aspx for more info on that.

I have checked the open relay sideof exchange server, but when I telnet I get connection refused. and I have checked the queues but do not seem to be any unusual ones. This however does not suprise me as we do not have port 25 on our router open for inbound traffic and we pop3 for incoming.

I have blindly tried restricting the sql srv as suggested by Jeff and have an idea this has corrected things, but what does the 70 figure represent?

sifenwick,

70 = 4MB which is plenty of RAM for that process.

Jeff I think we are there with this. Is there a way to limit exchange RAM as well?

There are a few things that can be done to tune Exchange's memory use... however, the /3GB switch (if you have more than 2GB of RAM is not recommended on an SBS.  I've tried it and haven't really seen any improvements.  However the other items can indeed help.
