1. During Setup server
Problem1: After execute "/domino/lotus/bin/server", show error: "could not backup notes.ini".
Potential reason: There are not enough disk space for server setup.
Potential solution: Please release some disk space.
Problem2: After execute "/V90/domino/bin/server", show error:" no protocol specified xhost unable to open DISPLAY: 0.0". or some other similar strings with "*** DISPLAY ***".
Potential reason: By default, XServer do not allow normal user(notes) to show its graphical program display on the screen.
Potential solution: root user execute the bellow command in a new terminal:
1) su root
2) xhost + （would show：access control disabled, clients can connect from any host)
3) su notes
4) /domino/lotus/bin/server (setup server again）
2. During Start server
Problem3: After start server, there would show " address already in use”or “ERROR: bindsock 'help application is missing, not executable, not setuid root, or not sticky bit set”
Potential reason: system sendmail is running
Potential solution: stop system sendmail.(Take redhat system for example)
1) service sendmail status
2) service sendmail stop
This would stop sendmail temporarily. If system restart, sendmail would start again. You could choose to close it permanently.
