When I type the command "dmesg", I see the following messages at the
tail end of the output:

in_rtqtimo: adjusted rtq_reallyold to 2400
in_rtqtimo: adjusted rtq_reallyold to 1600
in_rtqtimo: adjusted rtq_reallyold to 1066
in_rtqtimo: adjusted rtq_reallyold to 710
in_rtqtimo: adjusted rtq_reallyold to 345

My observation is that sometimes it will stay at 710 for about a week,
then it will drop to 345.  Ofcouse, after a reboot, the countdown will
start over.  Sometimes it take less than a week to get to 345.

J"org responded to a previous post similar to this one and stated the
following:

"It means your system accumulated too many clone routes within short
time, and thus finally dropped the timoeout in order to not waste too
much space in keeping them around.  Clone routes are network routes that
have been applied to a particular destination host to make routing more
efficient.  If they live for too short, your routing will be slower.
710 seconds doesn't look too short to me however."

My questions are as follows:
  1)  What value would be considered too short?
  2)  What are the consequences if this value gets to be too short?
  3)  How can I stop this countdown from occuring?


Thanks in advance for your help.
