Kernel memory exhaustion hotfix available – for Exchange 2003 SP2

When is a ‘fix’ not a ‘fix’? When it’s actually reducing the issue rather than actually ‘fixing’ it. It’s a little unfair but true .

If you run a large Exchange environment then you should be having a good look at the Kernel memory on your servers, especially if the users are members of lots of security groups. There are a whole load of posts from the Exchange team about this issue here, here and here.

A hotfix is now available with details here, linking to a KB article here. This ‘reduces’ the issue by about 30% – so not really a ‘fix’ but that was expected because the real constraint is the 32–bit architecture on which Exchange and Windows runs (for now) .
