I am trying to create 50 VNC display session on a CentOS 7.6 machine. I created a local user. Once logged in, I could create only 9 sessions.
After this VNC Server starts, immediately errors out with
Sample VNC log Copyright (C) 1999-2017 TigerVNC Team and many others (see README.txt) See http://www.tigervnc.org for information on TigerVNC.

dmesg has something like below…

I suspect this is to do with system limits for user or dbus limits. I am unable to proceed though. Please suggest what could be changed to create tens of VNC displays.
