After months of preparation, we launched a new SharePoint intranet portal today. Immediately, some users began getting a "server out of memory" error when they tried to log in. The SharePoint server appeared to be fine, but the SQL Server was reporting 100% memory use. (It has 4 GB.)
We rebooted the server and have not had further memory problems, though memory usage is hovering around 60% or above. I'm not convinced that we have solved the problem; I suspect it may return Monday morning when the whole staff tries to log in again.
I'm not a database guy, and I'm stumped about how to troubleshoot this. Do we need more memory, or is there somewhere I should look to reduce memory usage?
