SNMP V3 oddities in 2.2 alpha

[oliverm]

Hi

We're using 2.2 alpha (2.14 I think) because we need the authentication and privacy settings for some SNMP3 devices.

What we've noticed is that the SNMP 3 items eventually start showing an "incorrect password, community or key" error. They start monitoring normally and we get data back but leave them for a few checking periods and we get a red cross and that error.

I can test the data from the zabbix server using SNMP walk with the same details as the items and I constantly get valid data back.

I could almost understand it if the items never worked but its the fact that they work then error which is odd.

We can get them working again by deleting the template and re-importing it. At which point the data flows for a few periods then slowly they give us back the authentication error.

Anyone else seen this?

Here's an example of the flapping from the logs;
