During my testing with Clear-UDCache the physical memory still continue to grow, my dashboard setup is as follows:
1- scheduled endpoint to cache services using get-service command that runs every 10 seconds.
will Clear-UDCache works in this scenario to prevent Ram growing, if so how to use it in above example.
it will be nice also to implement a cache clear percentage like clearing 33% of the cache items so UD still populating the data from last cache and doing so will prevent the need for recycling the apppool more often or every night.
Thank you
No amount of cache clearing features will fix memory leaks etc. right?
Like the issues with endpoints not being destroyed, or simply bad code.
@PorreKaj
will in my scenario the cache will keep building up in memory cause am running it throw a schedule which is needed in my case cause if i did the cache 1 time then for example if a user start a stopped service it wont reflect the updated status since you have the 1 cache when the service status was stopped.
am trying to see if there is a solution that will prevent appPool recycle every so often and thought clear-udcache will do so but looks like clear-udcache is implemented to target something else
Sounds interesting, can ya share the problematic code?
I’ve personally dropped using schedules for data that needs to be near live. Ran into too many issues with cache.

Are the issues that the data isn’t consistent? The cache is now a simple dictionary rather than a MemoryCache object. It should give way more control over what is stored and for how long.
I’d be curious to see how you are using the cache as well.

below is my full code
