The problem: When running X programs to a remote X server, if the remote X server stops being available, the programs which were being displayed often stay running. This results in many stale programs running and using resources.
It appears that by default, xlibs opens TCP sockets to remote X servers without setting SO_KEEPALIVE. If SO_KEEPALIVE is set, the kernel will send periodic pings through the TCP connection. If the other end fails to respond for some time, the TCP socket is closed. If the TCP socket is closed by the kernel, will X apps also close, thereby freeing redundant resources? If this would work, can anyone consider a reason not to enable SO_KEEPALIVE? Are there run-time options for SO_KEEPALIVE or will the option need to be set at source level or compile time? If editing source code is required, is there one function responsible for opening all X TCP sockets, or would it be a complex task to edit Xlibs to enable SO_KEEPALIVE? _______________________________________________ Devel mailing list Devel@XFree86.Org http://XFree86.Org/mailman/listinfo/devel
