Cryptic error message

[dirk-zimoch]

Some error messages can be so cryptic:

Caught an exception creating the initial control telnet port: Bad file descriptor
/usr/local/bin/procServ: Exiting with error code: 98

What it really means:

Port xxxx already in use

Rule number one for error messages: Don't tell the user where the program could not continue (as the user does not know the internals of the program). Instead give the user a hint how to solve the problem.
