Livepatch freezing ubuntu

I am running Ubuntu 18.04.3 LTS with livepatch.

My computer often freezes for half an hour (or longer), at which point it seems swap and snapd are using all the cpu (quad-core) and ram (16 Gb). When it starts responding again, there is a message saying that livepatch has finished.

I am not happy with this and would like to restrict the times livepatch is allowed to hijack my computer... for instance, could it not update while I sleep?

Only other option I see is to remove livepatch from my main computer (not ideal either).

Any thoughts?

OUTPUT of sudo canonical-livepatch refresh

Before refresh:

kernel: 4.15.0-50.54-generic
fully-patched: true
version: "58.1"

After refresh:

kernel: 4.15.0-50.54-generic
fully-patched: true
version: "58.1"

So it seems livepatch IS successful but just takes all my PC resources to do its thing?

If you shut down and restart your computer occasionally, it's hard to see the point of livepatch. – Organic Marble Oct 24 '19 at 22:28
Could you add the output of sudo canonical-livepatch refresh. Check this related post – Pablo Bianchi Oct 24 '19 at 22:41

@OrganicMarble - Exactly, I do not regularly reboot my ubuntu PC. Perhaps once every 6+ weeks and only if I really have to. – cis Oct 25 '19 at 22:32
@PabloA Thank you for that link, but it does not seem to directly impact the issue I describe. – cis Oct 25 '19 at 22:33
