<div>I think that what you did is perfectly ok, but I think it would be better in the public algorithm, if the script will check if the session failed due to display and if so it will lock the display number for NX, and try again on the next free port. All this without failing the session, that is, it will try and try (up to max attempts) until it will be able to establish a session.<SPAN contentEditable=false style="DISPLAY: inline-block"></SPAN></div>

<div id=AOLMsgPart_0_5212452c-2834-448b-a9ea-2c630a7d76a3 style="FONT-SIZE: 12px; MARGIN: 0px; COLOR: #000; FONT-FAMILY: Tahoma, Verdana, Arial, Sans-Serif; BACKGROUND-COLOR: #fff"><PRE style="FONT-SIZE: 9pt"><TT>Hello, recently we've had some trouble with FreeNX under load not beeing able to start a new session, because the "stupid but working algo..." (comment from nxserver script!) was not really working. ;-) The problem was, that nxserver (in server_startrestore_session()) always tried to use the same $SESS_DISPLAY, which was locked somehow(?) - eventhough no lock-files existed. The reason for the "lock" could not be found. There were no processes left running from the user who last successfully used this display number. If we forced FreeNX to use the next display by manually "blocking" this faulty display number (touch /tmp/.X<displaynum>-lock) people were able to login again using the next free (working) numbers. The commercial NXServer uses another logic here: It does not search for the next free display number (starting from display-base) but instead always increments the display number, starting again at display_base when reaching the limit (round-robin). It uses /usr/NX/var/db/running/display.{last} for storing the last used display number. I modified nxserver to mimic this behaviour and hope there will be no more troubles in the future. Maybe this should generally be implemented in FreeNX this way?
