I'm using Nagstamon (https://github.com/HenriWahl/Nagstamon) which is QT based.

"sudo iotop -o" shows constant IO usage of nagstamon 2.0-beta-20160727, at least when there are new nagios alerts the nagstamon notifies with a flashing "N" symbol.

"watch -n 0.1 'ls -la /tmp/qt-trayicon*'" shows that temp files get created and removed quite frequently, and "mkdir /tmp/nagstamon; cp /tmp/qt-trayicon* /tmp/nagstamon" shows 2 png files with the nagstamon "N" symbol.

Please fix this if possible.

Here is the link to the initial bugreport i created for nagstamon: https://github.com/HenriWahl/Nagstamon
