Bug Description

From time to time this error is repeated in gnome-shell whrn I try to open a new program:

Maximum number of clients reachedFailed to open display
Maximum number of clients reachedMaximum number of clients reached/usr/lib/libreoffice/program/soffice.bin X11 error: Can't open display:
   Set DISPLAY environment variable, use -display option
   or check permissions of your X-Server
   (See "man X" resp. "man xhost" for details)

To solve it I have to reopen the session.
