|   Yes, it does exist - also SunOS4.1.2 on   Sun4/630MP.

  A common cause of monotonically growing routers is a looping message and
its error message.  If you start a loop either in routing a message or
reporting an error in it, the number of headers grows very large.
As all headers are kept in a memory structure, this causes sudden bloat!

  After 17 detectable loops or 100-odd (?) hops, the growth stops.

  I used to see this with 1.2 and still do when I botch things on a 2.x
system and start sending myself mail (:-))
