Hi Ruud,

You say you are using 256k DSL lines.  Are these on a public DSL network?
If so, I suspect you may be experiencing heavy contention, and therefore
packet loss.  SNMP, being a UDP based protocol will not tolerate any degree
of packet loss.

You could try running some form of VPN or tunnelling transport over the
links to ensure guaranteed end-to-end delivery of packets, to ensure the UDP
packets get there and back intact.

Regards,
Craig
