5.1.1 snmpd hangs on AIX 5.2, tcpip data missing

I built snmp using

./configure --with-default-snmp-version=3 \ --with-sys-contact="<contact>" \ --with-sys-location="<location>" \ --with-logfile=/var/log/snmpd.log \ --with-persistent-directory=/var/net-snmp \ --with-openssl=/usr/local/lib \ --with-perl-modules \ --disable-shared

OS version is 5.2.0.0.2 with gcc-3.3.3, build seemed to run successfully. No unusual error messages, make went fine after applying the double-quote fix in include/net-snmp/net-snmp-config.h. Command line tools seem to work fine as well.

After starting snmpd, I get the following messages in snmpd.log:

nlist err: neither tcpstat nor _tcpstat found.
nlist err: neither tcb nor _tcb found.
nlist err: neither icmpstat nor _icmpstat found.
nlist err: neither ipstat nor _ipstat found.
nlist err: neither ipforwarding nor _ipforwarding found.
nlist err: neither tcpDefaultTTL nor _tcpDefaultTTL found.
nlist err: neither udpstat nor _udpstat found.
nlist err: neither udb nor _udb found.
nlist err: neither rt_table nor _rt_table found.
nlist err: neither rthashsize nor _rthashsize found.
nlist err: neither rthost nor _rthost found.
nlist err: neither rtnet nor _rtnet found.

nlist err: neither in_ifaddr nor _in_ifaddr found.

"snmpwalk -v1 -cpublic localhost .1" hangs when it is trying to get the interface counters:

After that, the snmpd uses 100% CPU and has to be killed.

It seems there is some problem getting network data from the OS.

Do you need more information (config log etc.)?
