There might be a problem, but I'm not sure if this is due to mail formatting:

> ls_url
> "http://perfsonar.restena.lu:8080/xml-ls/services/LookupService";

This should be on one line. Configuration file parsing assumes that each new 
line cointains a new key-value pair. 

Can you launch the MP with --debug and --verbose flag and tell me, if it says 
something about LS registration?

Thanks,
Verena

P.S.: the bwctl plugin problem is solved. However, I have to update the old 
bwctl MPs running in JRA1, they are not working with the new plugin any more.
I'll let you know when everything is running correctly again.
