[Pkg-net-snmp-devel] Bug#420876: snmpd memory leak confirmed on i386-pae/xen

[Frank Schubert]

Package: snmpd
Version: 5.2.3-7


snmpd running for ~12 hours:
snmp     11673  0.0  1.3  14452  2932 ?        S    May02   0:00 /usr/sbin/snmpd -Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid

snmpwalk -v2c -c public <hostname>:
snmp     11673  0.0  1.4  14592  3072 ?        S    May02   0:00 /usr/sbin/snmpd -Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid

snmpwalk -v2c -c public <hostname>:
snmp     11673  0.0  1.4  14592  3092 ?        S    May02   0:00 /usr/sbin/snmpd -Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid

snmpwalk -v2c -c public <hostname>:
snmp     11673  0.0  1.5  14592  3344 ?        S    May02   0:00 /usr/sbin/snmpd -Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid

The system is snmp-monitored from cacti and nagios. After ~1 week the system slows down because of swapping. After /etc/init.d/snmp restart all is back to normal.

Regards,
Frank
