So everything log_print() outputs is an error? IMHO log_print is missing the
priority/severity parameter...
Comparing log_print(), log_error() and log_debug() I think that loggin code
could benefit from some refactoring.

Back on the subject:
I think "Using SCTP for communications" is informational, not error, just as
"closing connection to node 118" is probably notice, while "connecting to" /
"connected to" is probably info or notice, too.

Ulrich
