Description

Hi After several hours, suddenly sing-box crashes and panic happens. I tested multiple times with different multiplex protocol such as yamux and smux, but the problem still exists.

Reproduction

Client (ss-out) > Server_1 (ss-in and vless-out) > Server_2 (vless_in) The panic happens in Server_1

Server_1 Config:

i have very similar crash https://pastebin.com/XBDGZNC5 with this server config https://pastebin.com/6VZjFnVy on 1.9.1

@amirhosss why did you close?

BK8000L avatar Jun 26 '24 06:06 BK8000L

I removed the domain_strategy in the direct outbound, which helps it run for a longer period, but the panic occurred again. So I reopen it.

amirhosss avatar Jun 26 '24 21:06 amirhosss

@amirhosss it crashes randomly i don't think domain_strategy makes any difference
