Kill defunct xrdp session --- xrdp users cannot log on

xrdp is making a log diary about the session inside .xrdp* files stored into the user's home directory. It might happen some .xrdp* session files to be stored into /tmp/ or /tmp/.xrdp/. xrdp service is making a relation with this session files. So, in order to make a connection again when you have defunct processes, you have three options:

• to make a new connection using different resolution (works as a workaround, but I do not recommended it)
• to remove .vnc/sessman* files from the home dir of the affected user/s, xrdp* files in /tmp and /tmp/.xrdp/ for affected user and connect again. (recommended solution)
• to restart xrdp service which will clear up correlation with the session files. (recommended only if you can afford downtime of xrdp sessions :) )
