net-snmp on solaris 8

hello

I am running solaris 8 sparc.
I installed net-snmp 5.4.1 (compiled it from tar file).

When I do snmpwalk from another server, I receive a partial list of OIDs then it stops and gives 'timeout. No response...'
another snmpwalk will directly timeouts.

I compiled again the binaries with --with-log but the log file did not show any entry when this incident occurs again.

If I stop and start again snmp (/etc/rc3.d/S78snmp), I can reproduce again the problem.

Any idea please?
thanks

ksh -x /etc/rc3.d/S78snmp to produce more debug
