[Interest] QNAM::get() spawns three processess and opens file descriptors which I am unable to close

[gsmember gs]

Hi,I wrote a desktop app on Debian5. Right after the first manager->get() I opened pstree and htop:root at kvm2:~# pstree | grep votebotserver     |-screen---votebotserver---4*[{votebotserver}]
htop shows me 4 running processess as well.
I tried to kill them with following methods:

QNetworkSession session(manager->configuration());
session.close();
session.stop();reply->abort();reply->close();reply->deleteLater();manager->deleteLater();After a while (about 5 minutes) the running process amount was reduced to 3 (2 + 1 the main process).
But the remaining 2 processess started my get() were never killed.
And after 2 hours, running many requests, I hit the user limit of open file descriptors.
"lsof | grep resrv" gave me a bunch of open fd's:[...]

Also tell us how you found those processes, how you tried to kill them; how 
you found open file descriptors.
 
I also understood you're saying there's a leak. How did you diagnose that?
