** This issue has been resolved in ArcIMS 9.0.1. **After starting ArcIMS using "$AIMSHOME/qs_scripts/start_arcims script", ArcMap server processes (aimsserver.exe) do not start.
On the terminal where "$AIMSHOME/qs_scripts/start_arcims" script is executed the MainWin environment has been previously initialized by executing the command "source $AIMSHOME/../init_engine.csh".
Since the MainWin environment is also initialized by the "start_arcims" script, it sometimes leads to failure in the startup of ArcMap server processes.
