We are running Exchange 2000 with SP1 on a Windows 2000 Advanced Server box with all current service packs and security patches. Since we upgraded to Exchange 2000 we have an issue that the STORE.EXE continues to eat up memory (we have 1GB in this box) whenever the Windows 2000 backup, Veritas Backup Exec or NAI Groupshield accesses the store. It continues to chew up memory till it maxes out. The store does not release it back when this is completed. We have rebuilt the box twice and tested that this is an issue even without the Veritas BENT or NAI Groupshield installed. The only resolution we can find is cycling the services; but this seems prohibitive. Anyone else experiencing this memory issue (leak)?
