general protection fault error:0 in libpaho-mqtt3.a.so.1 [message #1820691]

Hello All,

I am using paho c++ MQTT version 1.4.15 on ubuntu 18.04. I had a working setup where I was able to send msgs to and from MQTT to my application for days. But that happened with QOS=0.

Now when I have changed this QOS = 1, I am getting frequent kernel traps in dmesg like:

traps: general protection fault ip: xxxxxx sp: xxxxxx error: 0 in libpaho-mqtt3a.so.1

With QOS=1, application sometimes run for a day and then it gives above trap.

Can anyone please explain what could be going wrong with QOS=1 ?

-Thanks,
S
