--- Comment #3 from Jacek Caban jacek@codeweavers.com --- It seems that the commit just revealed an unrelated problem. Existing connections are closed now when requested, while previously they were be kept alive. The question is why the server is stopped. There is also a crash (before stopping the server, so it might be related), where GetFirmwareEnvironmentVariableW is called with weird arguments.
Please attach tid,rpc,winsock,seh,relay,pid,process,thread,environ logs for further debugging.
