Hi I'm running into this the first time (which might suggest that something has changed, perhaps just the duration I'm able to keep running without rebooting?).
After running my laptop for a bit over 2 months, I've started getting, for example when running urxvt from another terminal: Maximum number of clients reachedurxvt: can't open display :0.0, aborting. Doesnt' matter which X app, any one will give the same error, and closing 1 app will allow another 1 to be opened. I've googled for 20 minutes, and while there are tons of bug reports for Ubuntu, Redhat, etc.etc., all of them go on forever without anyone pinpointing the real issue or finding a solution. xlsclients|wc -l tops out at 158, ls /proc/`pidof Xorg`/fd|wc -l at 256. This being such a round number seems to strongly suggest that it's tied to the number of fds. But why so low? xorg.conf does not mention any limit. # cat /proc/`pidof Xorg`/limits Limit Soft Limit Hard Limit Units Max cpu time unlimited unlimited seconds Max file size unlimited unlimited bytes Max data size unlimited unlimited bytes Max stack size 8388608 unlimited bytes Max core file size 0 unlimited bytes Max resident set unlimited unlimited bytes Max processes 31119 31119 processes Max open files 1024 4096 files Max locked memory 65536 65536 bytes Max address space unlimited unlimited bytes Max file locks unlimited unlimited locks Max pending signals 31119 31119 signals Max msgqueue size 819200 819200 bytes Max nice priority 0 0 Max realtime priority 0 0 Max realtime timeout unlimited unlimited us As you can see, max open files is the usual 1024. Thus this seems to be Xorg itself deciding to stop accepting connections. How can I increase it? Christian.
