Package: iftop
Version: 1.0~pre2-3
Severity: normal
Dear Maintainer,
since last iftop upgrade (probably iftop:i386 0.17-19 -> 1.0~pre2-2 ), I've
observe that iftop memory usage increase constantly.
I use "iftop" since many years, and I never observe this behaviour.
2 computers are affected (both under testing), and upgradinng iftop:i386
1.0~pre2-2 -> 1.0~pre2-3 (unstable .deb) does not fix issue.
- For first computer (gateway), I run "iftop" under a "screen" terminal: screen
-S iftop sudo iftop -i eth0
here the ~/.iftoprc
<iftoprc>
interface: eth1
dns-resolution: no
port-resolution: yes
show-bars: yes
log-scale: yes
promiscuous: no
port-display: on
use-bytes: yes
line-display: one-line-both
show-totals: yes
filter-code: not udp
sort: 40s
</iftoprc>

After killing iftop process, ~430m are free.
On this tool, a "torrent" client is running (I'm sharing Linux distros), so
this is open/close a lot of connections.
- For the 2nd computer (desktop), I've observe same behaviour, while I
copy/paste gigabyte of files trought NFS server.
2 "iftop" commands are started, one with a "screen" command, and the other
without a "screen"
