duplicate traps (probably due to some bug in netsnmp?)

Hello,

I have the following problem: when I send a trap using send_v2trap the
trap is sent twice. The Notification-PDU is sent twice from the net-snmp
library but I make only one call to the function send_v2trap(...). The
problem is random but occurs more frequently if snmpd is heavyloaded.

I searched on the net and I saw some threads on this issue and that was
fixed by increasing the timeout so I did:

netsnmp_ds_set_int(NETSNMP_DS_APPLICATION_ID,
NETSNMP_DS_AGENT_AGENTX_TIMEOUT,
10000000l);

Which should set the timeout to 10s. I still have the problem.

Am I doing something wrong? Is this a known issue? Do you have any other
ideas?

Thanks in advance,
ovidiu
