Hello,
The company I work for are currently having intermittent timeout issues on our main database server which has been occurring for the past few months. The server runs off a VSphere 5.5 host and the specification of the server is:
·Windows Server 2012 Standard
·2 x Intel Xeon E5-2667-v4 (2 x 4 cores)
·256GB RAM
·10K RPM HDDs for OS / SQL / Logs
There are two SQL server instances which run off the same box. The database sizes in total are around 360GB but only half of this is used regularly. On average we see roughly 5700 concurrent connections during the busiest part of our working day.
I've been monitoring the CPU and RAM on the box for the past two weeks and we constantly use 95 - 97% of RAM. We've also noticed that the CPU usage sits between 60 - 90% for SQL. Very often we see this spike to 100% CPU utilization...
