Hi, we are seeing deadlock when osquery extension is using multiple threads to share the extension client between them. Is the client is thread safe or we need to create multiple clients

It could help to provide more details about your scenario, such as which language client you are using.

We are using C++ OS query 4.5.0 and having multiple threads trying to communicate with the Core.

I'm not familiar with the C++ SDK but this is helpful for someone who may be able to assist you.
