It appears that there is an issue if the number of TCP connections is greater
than 1000 as is the case on our server.
# netstat -an | grep ESTABLISHED | wc -l
1907
As suggested by Oracle, I appended the following options for snmpd to disable
the TCP MIB at runtime and avoid querying the tcpConnTable:
snmpd -I -tcp
But, when running 'snmpwalk,' it appears that the TCP MIB is still enabled:
. . .
TCP-MIB::tcpConnRemPort.192.168.18.6.64494.192.168.18.6.7103 = INTEGER: 7103
TCP-MIB::tcpConnRemPort.192.168.18.6.64820.192.168.18.9.7107 = INTEGER: 7107
TCP-MIB::tcpConnRemPort.192.168.18.6.64952.192.168.18.6.7103 = INTEGER: 7103
Timeout: No Response from localhost
. . .
The Oracle Doc ID is 1357800.1
Any suggestions?
Best regards,
Shannon

Subject: net-snmp 5.4.1 on Solaris 11: snmpd becomes non-responsive
After enabling the net-snmp service, snmpd will run for a short period and then
become non-responsive. snmpwalk times out. The following message repeats over
and over in the log:
verbose:access:tcpconn:entry: create
Any ideas?
Best regards,
Shannon
