Sun gateway delay

We are using a SUN 4 running SUNOS 4.0.1. as a gateway between subnet and
the backbone.
Lately we noticed a very strange behaviour.
This is the configuration :
SUN3/50 SUN386i SUN4 SUN4 SUN4
A M1 B M2 C
| | | | | |
--------------------------------- ---------------
Subnet Backbone
A has some files mounted from C. On A we start a global "find" command on
the file-system mounted from C.
B is serving as a gateway.
On M1 and M2 we started etherfind with time-stamping.
In the first minute there is almost no delay between the packets generated
by A on the subnet and the packets generated by B o the back-bone.
After a certain time a delay is seen between the corresponding packets,
this delay increases until 5 seconds even.
It gives the impression that the gateway B needs 5 seconds between
accepting a packet from the subnet and sending it through to the
backbone-net.
Has anyone else already seen this ? Are we measuring in the wrong way or
is there really a problem ?
