hi @Kernal-GH could you give more details, I want to know how "crash" mean? BTW, if you can privide [nginx debug log](http://nginx.org/en/docs/debugging_log.html) during crash, this can help me resolved this...

delay to reproduce this in windows by meself, wait more details of debug info.

hi @loory * Not familiar how to debug windows system, could you try some debug tool to get crash stack tracing info ( like linux gdb backtrace)? * Also check...

hi @loory It will be close to locate this crash issue. From your backtrack info, I guess the crash may occurs for some error logging operation( it may call ngx_write_fd...

Could you show the `buf` string of `nginx.exe!ngx_write_fd(void * fd, void * buf, unsigned int size) Line 184 C` and show `*r` variable.

Also you can try one-step trace via vscode. I found the following log_error in ngx_http_process_request_uri. ``` ngx_log_debug1(NGX_LOG_DEBUG_HTTP, r->connection->log, 0, "http uri: \"%V\"", &r->uri); ngx_log_debug1(NGX_LOG_DEBUG_HTTP, r->connection->log, 0, "http args: \"%V\"", &r->args);...

think it resolved. feel free to reopen if u still have the same problem

Currenty this variable not work for proxy_connect module. > If not, can this feature be supported? Yeah, we can add new variable `$proxy_connect_first_byte_time` similar to stream module.

See this pr: https://github.com/chobits/ngx_http_proxy_connect_module/pull/228

pr has been merged into master. `$proxy_connect_first_byte_time` doc: https://github.com/chobits/ngx_http_proxy_connect_module#proxy_connect_first_byte_time
