I cannot open MEDM sitemap from the dock.

When I click the  terminal  icon in the dock, a terminal window opens immediately but it takes more than 5 minutes before bash prompt is shown.

When finally the bash comes up, a simple ls command takes 3 seconds.

sitemap command from bash tries to launch something, and it takes about a minute or two before "cannot access file: /opt/rtcds/lho/h1/medm/SITEMAP.adl" is displayed.
