Well, I've noticed it first when I changed my router policies. From a computer 
I was telnetting a remote host on another subnet. The subnet was reached thru 
a Linux gateway connected to two routers (call them R1 and R2). In a first 
test R2 was down, so all the traffic was traveling over R1. When R2 was up, 
the traffic to the above subnet was redirected to the R2 router (i.e., I 
changed the 'route' policy of the gateway). Nevertheless, for a couple of 
minutes the traffic was going over R1.
Another issue I've noticed was an error on the /etc/hosts (different machine): 
I wrongly wrote  the address of an host, thus pinging it was a real ping to 
another machine. I correct the entry and re-do ping, but it was still pinging 
the wrong host. After a minute everything was working fine, but immediately 
it was not. I believe it could be an arp cache problem, as you suggested me.
Thanks,
Luca
