[Bug]: OpenSearch Vector Store have a lot of connection problem after #11513

[rendyfebry]

Bug Description

I noticed that after #11513, my OpenSearch vector store connection became unstable, and we can confirm this by trending bug reports related to this issue recently. (#13358, #11661, etc)

• This event loop is already running.
• ConnectionError(Timeout context manager should be used inside a task) caused by: RuntimeError(Timeout context manager should be used inside a task)
• etc

I also see it suggested to use asyncio, but even with that we can still get the errors

import nest_asyncio
nest_asyncio.apply()

I also notice, this error getting worse when we use LlamaIndex with FastAPI,

Version

latest

Steps to Reproduce

Just use OpenSearch vector store long enough that you'll notice it's become unstable.
