#774 snmpd infinite loops after walking Host MIB

[Ed Ravin]

Environment is NetBSD 1.5.3 and 1.6.1

Both net-snmp 5.0.6 and 5.08 have this problem in our
environment: when I do a MIB walk of the Host mib,
snmpd
goes into an infinite loop after returning these values:

We are running snmpd listening on tcp:NNNN and
udp:161.

The results of the walk are below:

snmpwalk -v 1 -m ALL localhost host
[...]
host.hrDevice.hrFSTable.hrFSEntry.hrFSAccess.1 =
readWrite(1)
host.hrDevice.hrFSTable.hrFSEntry.hrFSAccess.2 =
readOnly(2)
host.hrDevice.hrFSTable.hrFSEntry.hrFSBootable.1 =
true(1)
host.hrDevice.hrFSTable.hrFSEntry.hrFSBootable.2 =
false(2)
host.hrDevice.hrFSTable.hrFSEntry.hrFSStorageIndex.1
= 1
host.hrDevice.hrFSTable.hrFSEntry.hrFSStorageIndex.2
= 2
host.hrDevice.hrFSTable.hrFSEntry.hrFSLastFullBackupDate.1
= Hex: 00 00 01 01 00 00 00 00
host.hrDevice.hrFSTable.hrFSEntry.hrFSLastFullBackupDate.2
= Hex: 00 00 01 01 00 00 00 00
host.hrDevice.hrFSTable.hrFSEntry.hrFSLastPartialBackupDate.1
= Hex: 00 00 01 01 00 00 00 00
host.hrDevice.hrFSTable.hrFSEntry.hrFSLastPartialBackupDate.2
= Hex: 00 00 01 01 00 00 00 00

Our environment (both NetBSD 1.5.3 and 1.6) is available
for remote login if you would like a shell prompt to test
anything. Contact me at eravin@panix.com

If you could run the agent as snmpd -f -L -Dall you will get
a lot of debugging output -- it would be useful if you can
isolate where the repetition starts and either paste or
attach it here.

I realized that I had a mismatch in my environment - I was
running a net-snmpd compiled for NetBSD 1.6 on a 1.5.3 box.
I am unable to reproduce this problem when I match the OS with
a net-snmpd compiled for that OS.
