Hi Alexander,
I guess this bug is similar with this one on Redhat bugzilla :
https://bugzilla.redhat.com/show_bug.cgi?id=782275
I've start 2 "iftop" programs, one with "-n" parameter" and nothing for
the other.
"-n" mean that iftop will not try to resolve IP address :
$ ps -edf|grep iftop
root 26181 26151 1 00:06 pts/4 00:13:25 iftop -i eth0
root 26258 26059 1 00:06 pts/0 00:13:16 iftop -n -i eth0
^^^^^
Result with "top" :
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
26181 root 20 0 32668 4380 3324 S 5,3 0,2 13:18.14 iftop
26258 root 20 0 797m 461m 3340 S 3,3 26,0 13:11.00 iftop
^^^^^ ^^^^ ^^^^
After 24h, "iftop -n" command use about 800m, since other "iftop" only
use 32k.
So, this is look like that memory leak appear when DNS resolution is
OFF.
In my ~/.iftoprc , I use;
<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>
I've run iftop under valgrin control (see attachment), but he did not
found many leak :
==11872== LEAK SUMMARY:
==11872== definitely lost: 3,446,706 bytes in 143,983 blocks
==11872== indirectly lost: 0 bytes in 0 blocks
==11872== possibly lost: 6,264 bytes in 247 blocks
==11872== still reachable: 169,197 bytes in 2,264 blocks
==11872== suppressed: 0 bytes in 0 blocks
==11872== Reachable blocks (those to which a pointer was found) are not
shown.
==11872== To see them, rerun with: --leak-check=full --show-reachable=yes
==11872==
==11872== Use --track-origins=yes to see where uninitialised values come
from
==11872== ERROR SUMMARY: 16 errors from 16 contexts (suppressed: 27 from 8)
So, I guess that iftop does not really "leak" memory, but allocate new
memory every time.
I've **downgrad** iftop (1.0~pre2-2 -> 0.17-16), and issue does not
appear:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
32479 root 30 10 29608 3476 3112 S 0,3 0,2 16:51.97 iftop
So, I guess this bug appear during during 0.17-16 -> 1.0~pre2-2 upgrade.
Best regards,
Olivier
