Memory leak when writing intensively

I have a memory leak problem writing to kinesis from node and I wanted to verify if it happens as well with this sample producer.

I verified that if instead of 10 writes, you modify the code to write endlessly 10 times per second, the memory consumption grows slowly but steadily.

Any idea why this happens?

Start by reproducing the sample producer behavior described in the issue: change it from 10 writes to continuous writes at 10 per second and monitor memory consumption. Done means the memory growth is understood and the producer remains stable during a sustained write run.
