Memory Leak within load_ssl_context_verify when using openai-python

[vasudua]

Description

langchain initialises an openai-python instance which in turn defines a default httpx client something like here when a custom http_client is not passed as an argument to the class initialization. And this httpx client defined continues to hold memory even after the parent object is destroyed.

The place where the memory is being held up is load_ssl_context_verify, memray results follow.

As shown in the above screenshot, it is holding ~88 MBs of memory. This memory keeps growing with each new instance of the above classes created and never gets released even when the parent objects of the above mentioned libs are destroyed.

Expected Behaviour

The memory should be released once the parent instances are destroyed.
