Intermittent out-of-memory errors on web server
Symptoms
Occasionally the web server crashes with an out of memory error. There is no specific activity causing this, it just happens from time to time. Sometimes it's stable for a few weeks and sometimes just for a day, it seems to be random.
When this happens, a restart of the Changepoint Enterprise application pool resolves the problem.
Resolution
1. Make sure the web server has enough free memory available. The application pool must be able to grow to 2 GB, but the total memory for the web server needs to be much higher, as there might be other activities going on in parallel and other application pools are being used (API, Report Designer, ...)
2. In IIS Management Console, open the Changepoint Enterprise application pool advanced properties and change the recycling setting (Regular Time Interval (minutes). By default this is 1740 (=29 hours). Please select a lower value, like e.g. 480 (=8 hours). A restart of the application pool will cause a minor performance hit, but it will remove any memory fragmentation and other internal details that could result in an out of memory error.
