DSP Job list expanding

We are getting these warnings
[FMOD] DSPJobList::addJob : DSP JobList expanding job from 1024 entries to 2048 entries
[FMOD] DSPJobList::addJob : DSP JobList expanding job from 2048 entries to 3072 entries.

I have looked into when it expands and it is very busy locations were we have around 250 virtual voices and i estimate that they each are putting around 8 things in that list so it makes sense that it gets expanded.

And reading this thread How do you configure the starting DSP Job List Size? - #3 by Ryan_HardballGames it says that you can set its size using advancedSettings.DSPBufferPoolSize and im setting it to 3072 but im still getting the above warnings.

Is there any way to actually increase the size of the job list and what is DSPBufferPoolSize?
