Cache - Array dimensions exceeded supported range

[Jonsapps]

We have a project that uses MSharp originally created by Geeks Ltd. We have found that in recent months our production site is crashing periodically due to the size of the MSharp Database Cache exceeding the array dimensions set by C#.

I have recently upgraded MSharp to the latest version in the hope this would resolve the issue, unfortunately the issue remains. At present the only way we are able to resolve the issue is to restart IIS. This seemingly clears the cache and starts fresh, then in a few days the same will happen again. I cannot find any specific information regarding the cache in the documentation or any hints on how we can control what caches and what doesn't, it seems every database object is cached and as the project and database grow we are hitting the array limits of the cache sooner and sooner.

Can you clarify if this is expected behaviour and whether there are mechanisms available in the framework to allow us to control which database objects are cached.

MSharp Version: 4.0.201

Stack Trace from a crash when the cache exceeds the arrays dimensions:

Error: Array dimensions exceeded supported range.
