Package: snmpd
Version: 5.2.3-7
Severity: grave
Justification: renders package unusable
snmpd is running at 100% CPU on 2 of my systems, and will not respond to
polls. I have tried the default config file, which has the same effect.
After restarting the daemon I can snmpwalk up to (ip's modified):
IP-MIB::ipAdEntBcastAddr.127.0.0.1 = INTEGER: 0
IP-MIB::ipAdEntBcastAddr.172.16.0.1 = INTEGER: 1
IP-MIB::ipAdEntBcastAddr.192.168.35.4 = INTEGER: 1
IP-MIB::ipAdEntBcastAddr.1.2.3.4 = INTEGER: 1
IP-MIB::ipAdEntBcastAddr.1.2.3.5 = INTEGER: 0
IP-MIB::ipAdEntBcastAddr.1.2.3.6 = INTEGER: 0
IP-MIB::ipAdEntBcastAddr.1.2.3.7 = INTEGER: 1
Timeout: No Response from sys.tem.host.name
After this the daemon goes to full CPU in a loop, strace loops this:

ad infinitum.
Particular at these 2 systems is they both have a full routing table:
# ip route ls|wc -l
217705
I don't know if that has any influence.
