Description Danny_Johnston 2001-03-07 19:20:00 UTC

Problem was noticed when remote user could not pop mail from mailserver.
The route table appered to have 256 entries in it and route for new host
would not clone.  Tmp fix was to delete all cloned routes from route
table.

How-To-Repeat: Have not attepted to recreate problem, but it has happend three or four
times.

256 entries in the routing table is not high.  Make sure you 
have `maxusers' set to a high value, or tune network buffers 
with the NMBCLUSTERS option. 

See with `vmstat -m' who "eats" memory. 

If the problem is with too many cloned routes, try setting the 
net.inet.ip.rtexpire=0.
