Export oddity - two /snmp blocks

Has anyone seen this behavior?

[user@router] > /snmp export

Yes, I realize the OS is a couple revisions out of date. That’s verbatim what I get when I run an export – the /snmp export, the /snmp community export, then the /snmp export again. OS is running on a 450G with current firmware as of 5.4. SNMP had become completely unresponsive on the device, hung on an export for ~60 sec at the snmp section, then started exporting properly but repeating the SNMP.

Was seeing other issues as well – interfaces not displayed in winbox, some OSPF propagation issues on the network suspected to be due to the router. After a device reboot all the symptoms seem to have been cleared up aside from still outputting two /snmp exports.

The changelog for 5.6 shows 2 fixes related to SNMP (though not this bug, but MT change logs aren’t exactly exhaustive) - I’d try upgrading.
