It appears that the xorp_igmp process has died (confirmed by
your "ps" output), and the xorp_fea process is in funny state if it
doesn't respond to "show interfaces" and "show mfea interface".
My best guess so far is that something went wrong with the xorp_fea
process so it doesn't communicate properly with other processes.
The disappearance of the xorp_igmp process may be related to this.
The "show mfea interface" doesn't work, because the MFEA itself is
part of the FEA process.

I presume now you have enabled the log messages, so lets hope they
will give us some useful info next time you have the same
problem. Also, next time please include the output of "ps -auxww",
because it includes more info like the particular state of each
process.

P.S. Your configuration seems fine.
