We have ArcGIS 10.3 installed on Linux 14.x and facing following problem according to xvfb_err.log file:
_XSERVTransSocketINETCreateListener: ...SocketCreateListener() failed
_XSERVTransMakeAllCOTSServerListeners: server already running
Fatal server error:
(EE) Cannot establish any listening sockets - Make sure an X server isn't already running(EE)
Did anybody find a solution for this?
