           Summary: net/mpd5: crashes host when configured with PPPoE
           Product: Ports & Packages
           Version: Latest

Running a small router/ipfw appliance based on recent FBSD 14-STABLE (former
13-STABLE when the problem occured first time).

When mpd5 is configured using PPP/PPPoE, a simple

service mpd5 restart

can crash the box. The problem becomes more likely the longer the appliance is
up and running.

There was a thread about this icident on the mailing list more than a year ago
with some debuggin informations, I'm sorry not providing any further
informations. The router/ipfw appliance is connected via serial console to a
service host and I was unable so far to snapshot the debug message.

I was wondering whether this issue has been solved or not - obviously, it even
not documented here.
