Package: snmpd Version: 5.2.3-7etch4 Severity: important
The default etch install of snmpd with default config will leak memory if there is 1 or more VLAN ethernet interfaces on the system. This appears to be a regression between sarge and etch. After some investigation I've found: * leak occurs every 60 seconds * leak occurs at a rate of 1094KB/day _per_ VLAN interface * rate of leak is directly proportional to the number of VLAN interfaces * leak occurs even if no snmp activity is happening (get, set, get next, trap, etc..) * the VLAN interface must have an IPv4 address assigned * the VLAN interface can be either UP or DOWN * the name of the VLAN interface doesn't matter How to recreate: apt-get install vlan add to /etc/network/interfaces: > iface eth0.100 inet static > address 10.2.100.1 > netmask 255.255.255.0 > broadcast 10.2.100.255 ifup eth0.100 watch snmpd grow... start of test: USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND snmp 1886 0.0 0.7 6784 3860 ?
