Websocket example #2917

Open Dimitrius-dev opened 1 month ago

Dimitrius-dev commented 1 month ago

Hello, Boost=1.84.0, BOOST_BEAST_VERSION=351 I am using boost/beast websocket TLS async client example link. I noticed my connection disconnects sometimes with stream truncated and eof. What do these errors mean? I checked my internet connection with wireshark and it's fine.

Do they happen at the end of stream? error::stream_truncated

Dimitrius-dev commented 1 month ago

No, i get these errors without calling any shutdown or disconnect function. And it shows when use client for high load traffic (high frequency).

Are you sure it’s not the server that dropped the connection? Does this happen with just one specific server?

Dimitrius-dev commented 1 month ago

Can connection issues occur if multiply connections use load_certificates function?

ashtum commented 1 month ago

Do you mean load_root_certificates? it calls ssl::context::add_certificate_authority which is not thread safe.

Dimitrius-dev commented 1 month ago

I made n threads. Every thread has its own asio context, and interact with the same internet resource

ashtum commented 1 month ago

Do they have their own ssl::context too?

Dimitrius-dev commented 1 month ago

yes

Have you tried reducing your application to a single connection and a single thread to see if the issue still exists? If possible, test one of the existing examples.
