Public bug reported:
Here are several Ubuntu 7.10 server, them have snmpd. Snmpd runs with
this options:
/usr/sbin/snmpd -Lsd -Lf /dev/null -u snmp -I -smux -p
/var/run/snmpd.pid
After few days, on those systems the size of free memory looks like
decrease (we look them with several tools, like cacti, and top also
shows up, snmpd eats about 3-4% of total memory).
Here are some output when I have restarted snmpd:
# free
total used free shared buffers cached
Mem: 775568 567488 208080 0 190412 119996
-/+ buffers/cache: 257080 518488
Swap: 979832 0 979832
output of top:

-/+ buffers/cache: 103192 672376
Swap: 979832 0 979832
After the restart the top command shows up:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
28655 snmp 15 0 7500 4320 2376 S 0.0 0.6 0:01.09 snmpd
When we sense this first time, one of those systems has crashed - the system
has ran out of memory.
After this affair we look those systems, which has snmpd, and restart the
service on every week.
We didn't find with this effect on any other Linux (including Ubuntu)
version.
Any suggestion?
