The presence of error messages usually means the program has spotted an
exception and handled it.  There may have been abnormal traffic on your
PPOE connection but pppd caught it.  However, the possibility does exist
that some problem traffic was not identified and handled.

In addition to running chrootkit you may wish to start running tripwire
(if you don't already).  Tripwire usually helps greatly in spotting file
system abnormalities...
