I was seeing the same unicode characters for IPv4 and IPv6 neighbors coming from Cisco ASR 9000 routers running IOS-XR 4.1.2.
I updated to latest SVN after seeing these emails and they are now displaying properly for me.
Not sure if similar bug in IOS-XR but I will investigate.

Hi Mike,
I have routers with version: IOS XE Version: 03.06.01.S, Version 15.2(2)S1 and: IOS XE Version: 03.08.01.S, Version 15.3(1)S1. Both have the same problem. The bug you describe is about a memory leak. In version 3.6 - 3.10 I can't find anything about a bug (or fix) for the SNMP issue. If I check a router with the 3.6 version code, it is giving the IPv4 BGP neighbor ip addresses correctly, the IPv6 addresses are corrupt or empty (as seen in the screenshots from yesterday). For the 3.8 version code, it looks like the IPv4 ip addresses are wrongly formatted, this could be an IOS bug. But the IPv6 problem is the same for the 3.6 and 3.8 version IOS.
Could you please see if you can fix that (ipv6 part) in Observium code? The version 3.8 I will try to upgrade to see if the problem with the wrongly formatted IPv4 addresses will be fixed.
Regards,
Bastiaan

Hi Mike,
Hereby the discovery output.
In our case it is ASR1001 router with Cisco IOS-XE 15.2(2)S1 (UNIVERSALK9).
Another tip, as it looks like a bug in IOS-XE, I suggest you update to the latest stable version. Latest for IOS 15.2 - Release 3.7.4S (asr1001-universalk9.03.07.04.S.152-4.S4.bin)

Hi,
I have kind of the same problem, but this time with Cisco ASR routers. As you can see below.
I included the poller debug outputs.
Ohh, nice. Thanks for debug outputs!
Please send also debug out for discovery. And tell ASR model and OS version.
The correct output (from a Cisco IOS router):
bgpPeerLocalAddr
bgpPeerLocalAddr.149.14.34.41 = 149.14.34.42
bgpPeerLocalAddr.172.30.253.3 = 172.30.253.66
bgpPeerLocalAddr.172.30.253.4 = 172.30.253.66
The wrong output (from a Cisco ASR router):
cbgpPeer2LocalAddr
cbgpPeer2LocalAddr.20." ..|(..........." = "20 01 06 7C 28 D4 00 00 00 00 00 00 00 00 00 03 "

cbgpPeer2LocalAddr.ipv4."172.30.253.4" = "AC 1E FD 03 "
cbgpPeer2LocalAddr.ipv4."172.30.253.33" = "AC 1E FD 03 "
cbgpPeer2LocalAddr.ipv4."172.30.253.34" = "AC 1E FD 03 "
cbgpPeer2LocalAddr.ipv4."172.30.253.65" = "AC 1E FD 03 "
cbgpPeer2LocalAddr.ipv4."172.30.253.66" = "AC 1E FD 03 "
cbgpPeer2LocalAddr.ipv4."172.30.253.67" = "AC 1E FD 03 "
It looks like Observium is showing the first output correct, but not the second. Can this be fixed someway?

Anyway, please send an output for debug poller/discovery.
