[SNMP4J] Strange exception

[Sasa Markovic]

Hi,

I have recently discovered SNMP4J and I want to say that this library is 
much better than any other free SNMP library. I have managed to port my 
existing java code to SNMP4J very quickly, but from time to time I get 
the following strange exception:

==========================================================

         at org.snmp4j.smi.Variable.createFromBER(Variable.java:120)

============================================

I am using PDUv1 to sample some standard OIDs (ifInOctets, ifOutOctets 
and similar) - nothing more complicated than that. To make things more 
strange, this exception gets printed on the screen only from time to 
time - it does not appear on every SNMP request targeting the same OID 
on the same host. However, my application seems to be working properly 
but this exception is quite annoying.

Thanx for the help.

Best regards,
