Yeah, the problem is that the daemon is detecting the illegal name at an 
unexpected point and is giving up.  My point was that if the daemon name 
is too long it should give up even before it starts running so that this 
problem could never be encountered.

Usually if the user gives too long of a private name such that 
#app_name#hostname would exceed the predefined limit, the app_name is 
truncated so that it can fit in the predefined limit.

In short, I believe that an integrity check that should be done on 
startup on the daemons' names isn't being done correctly.  Or this could 
be a symptom of a completely different bug, we'll try and find out.

No, I didn't have this email address subscribed to the list, my initial 
response should show up there shortly.
