I just did an lsof myself, and don't have these entries. The worrying 
part is the "can't identify protocol". Does anybody know what could 
cause that?

As other people have mentioned this is from the weather plugin. I do use 
it as well and don't see any open files. It almost looks like your 
system has some trouble closing file descriptors, but I have no idea if 
that is even possible.

What happens if you restart the panel (right-click on a handle -> Restart)?

Sorry, I still have no idea about the cause.
