Out Of Memory when writing lots of datapoints

Hi,
We are having an application that crashes with an OutOfMemory exception.

We are having trouble when writing data to Influx with the "WritePoint" method.
We are writing ~2000 datapoints per 10ms per thread(there are 2 threads at this point in time writing data).
When writing these datapoints memory keeps piling up by 10mb per minute and never going down untill we stop writing for a short while or eventually hit an OutOfMemory.
Setting the FlushInterval higher seems to migitate the problem, but memory still increases(albeit at a slower rate).
Using only one thread for writing data also migitates the problem, but it takes 3 days to run out of memory.

We are using:
Client version: 4.0.0.0
InfluxDB Version: 2.1.0
Platform: Windows 10 (different systems with different specs).
FlushIntervals used: 10, 500, 1000, 2000.

Would it be possible to improve the API that the API notices that it cannot handle the load?
