[Pkg-net-snmp-devel] Bug#500717: Bug#500717: snmpd reports assert in syslog and does not return data

Jochen,

>> Since upgrading from etch (stable) to testing, snmpd is reporting this in syslog:
>> Sep 30 06:25:22 quark snmpd[4507]: netsnmp_assert rc == 0 failed if-mib/ifTable/ifTable_data_access.c:210 _check_interface_entry_for_updates()

At restart this happened:
Oct  2 16:38:11 quark snmpd[4720]: netsnmp_assert rc == 0 failed 
if-mib/ifTable/ifTable_data_access.c:210 
_check_interface_entry_for_updates()
Oct  2 16:42:15 quark snmpd[4720]: Received TERM or STOP signal...  
shutting down...
Oct  2 16:42:17 quark snmpd[4033]: netsnmp_assert !"registration != 
duplicate" failed agent_registry.c:535 netsnmp_subtree_load()
Oct  2 16:42:17 quark snmpd[4033]: NET-SNMP version 5.4.1

But it does no longer repeat the assert. Now that you mention this, I 
have to report that previously (i.e. etch snmpd) would crash at reboot.

This is the full list of ubuntu packages: findutils, libc6, libc6-i386, 
libxen3, python-xen-3.3, xen-hypervisor-3.3, xen-utils-3.3.
In reality this is because I want to run xen 3.3, which requires the 
newer libc, libxen3 and python-xen-3.3.

But I'm just using the regular startup scripts that came with the packages.

Did I already mention that this is a xen dom0? I.e. after startup, 
network interfaces appear to connect to the domU instances, the physical 
ethernet gets renamed and a bridge gets added. So perhaps that's a bit 
complex for snmpd? I don't know.

If there's something I can do to help, like get you a crash dump or a 
backtrace with gdb , please let me know (I'm a programmer myself, just 
no experience with snmpd).

Thanks,
Jan Evert
