Extensive memory consumption using PullUp-Functions

Hello and a happy new year,

we do have the problem of memory allocation while using several Pull-Up Aggregations. Is there a way to release the memory frequently?

Our set up is Hybrid (IBC + Leave your data in place).

We have 90mio Activities@8.5mio Cases in one Model and 260mio Activities@24mio Cases in a second Model. The memory consumption is in idle state at 24 GB and moves up to 64 GB when using PU-Functions. This will quite often let the engine crash and models could not be re-loaded even from cache until the memory garbage is cleared.

Thanks for any suggestion.
