DOUG Immediately Returns with no error

"I run doug and it immediately returns to the command line with no output and no errors."

• Try making sure that the environment getting loaded is specifying a good config file. This is normally done by setting $DSP_CONFIG_FILE and $DOUG_CONFIG_FILE but it can also be done on the command line. Make sure the file exists and has sufficient permissions to be opened and read.

• Make sure the config file is well-formed. Look for missing brackets and other problems.

• Try removing user customizations and see if the problem goes away. If so, add on customizations one at a time to find the culprit.

• Try running with the "-verbose" option. This may allow you to see at what point it is actually dying. Sometimes this can be caused by an error loading a particular model.
