Hi Dave,
Sorry, here is our makefile

ifeq ($(CONFIG_IPV6),y)
SNMP_TRANSPORTS_INCLUDED+= UDPIPv6
CONFIGURE_ARGS+= --enable-ipv6
endif
So as mentioned before when I remove the lines
--with-out-mib-modules="$(SNMP_MIB_MODULES_EXCLUDED)" \
--with-mib-modules="$(SNMP_MIB_MODULES_INCLUDED)" \
udpTable works fine. But the size of the
libnetsnmpmibs.so seems to double(built with symbols) with this change. So I am
planning to go back to including them again and insert MIBs one by one and see
which MIB inclusion is causing the segfault.
Thanks and Regards,
Malathi

I have no idea.
You have haven't said anything about what modules are currently being
included or excluded, and hence what changes you are making to the
configuration.
You're obviously using some setup other than the basic Net-SNMP distribution,
since our setup doesn't look like the fragment above.
You'll need to look at that Makefile, and see what the setting for these two
variables currently are. Then think about whether adding or omitting these
particular modules is important for your requirements.
