Description (partial)

Proxy process size grows too large and the process gets killed by our monitoring process due to
memory limit violation.

The box is under high HTTPS traffic but is not able to move the data fast enough, leading to
accumulation of allocated buffer for HTTPS traffic. Due to how our internal memory allocation
(malloc) module manages page memory, the proxy process size does not reduce even after the high
HTTPS traffic load stops. Eventually  when the process memory size grows beyond a certain
limit, our process monitor kills the process.
