Gregory,

This is strange, the only thing I can think of is that the 5.0.8 version
is receiving more AFOS data.  The irix system sometimes get into confused
states when the queue is expanded.  I would make the queue 150 megabytes
and try again. If the message still appear, make the queue large until the
messages disappear.  The comments in RCS for the afos_message.c state that
the routines where made more lenient to allow more products to be
accepted.
