<p>I have been getting the same error once or twice after a prolonged period of time since version 1.3.5. I also got it now again in 1.3.7. I was just too lazy to report it previously.<br>
Honestly, there is something wrong here.<br>
and yes i have 32GB RAM, so its not a memory problem. Not a VM.</p>
<p>Xubuntu 18.04</p>
<p>Below log</p>
