Application is hanged after running for more than 1 hour

[sangngocle]

I am using a VM with ubuntu 18 image. I've cloned and rebuilt the latest commit in master branch. I tested with CANraws and CANsignals module. The issue happens when I left the application running through for more than 1 hour, and other apps which are running are hanged as well. The issue only disappears when I close all the apps and restart them.
