vncserver problem

karpoand · 11-11-2008, 11:28 AM

Hi!
I'm running vncserver on Red Hat Enterprise Linux 4.0.
I have a problem when I open 250+ applications accessing vncserver it throws an error:

Xlib: connection to ":2.0" refused by server
Xlib: Maximum number of clients reached

Please help me on solving that issue. I need to launch at aproximately 500 applications but actualy at this time it can manage only 265.

Regards,

Andrejs

any suggestions?

Are you opening a separte connection(VNC session) for each app?

nope, everything in one session!

Well you could try opening multiple sesions (from the same machine) to bypass the issue.

It might also help to know what types of things you are running. You MAY be able to write a script(server side) that opens a lot of the apps but is seen as one app (the script) by VNC's counter. Purely a guess as I have never had to open over a few apps at any one time(over VNC).

no, u didn't understand. i need to launch all these applications stricly in one vnc session! i've tryed to simply launch 250 xclocks in one session and on 237 xclock this error occures. I seems that I need to increase these client number. Please,can anyone help?

Why does it HAVE to be in one session?

karpoand · 11-13-2008, 02:38 AM

beacause many users are connecting through this session and therefore there need to be open a big amount of programs

That was my point. Split the users up over several sessions. Each individual session can open 255(roughly) processes. If you need 500 then open two sessions, if 750 then open three, etc. Otherwise I think you will have to completely rewrite VNC to use two(0-255) rather than just one(probably a lot of work).
