TWebSocketAsyncServer hangs when application is terminated

dcoun · 2022-02-13 17:51:40

Delphi 11, win32 target, mormot2

A TRestHttpServer with two TRestServerDB/WebSocketsEnable

when destroying it:
srv.shutdown; (the TRestHttpServer)
srvdb.Free; (one TRestServerDB)
oper.Free; (second TRestServerDB)
srv.free;

The TRestHttpServer hangs at file mormot.net.ws.async, line 597,

    // use TWebSocketAsyncConnection.SendDirect for non-blocking socket sending
    if aClientsConnectionID = nil then
      // broadcast to all connected clients
      for i := 0 to fAsync.ConnectionCount - 1 do
        inc(result, ord(TWebSocketAsyncConnection(fAsync.Connection[i]).
           SendDirect(tmp, aFrame.opcode, aTimeOut)))

In the logs,

Do you use them from WS clients, or regular REST clients?

forgot to tell
From Regular rest clients is OK. This happens with Websocket clients connected before.
