Saw the same on several systems, even while I'm typing this:

I can also confirm this bug. Muon spawns an infinte number of apt-check processes.
I would consider this bug extremely severe, as it massively spoils a systems stability and performance.
The problem occurs with Ubuntu 15.10 when upgrading with ppa:kubuntu-
ppa/backports to muon version 5.5.3.

here too. muonupdater 5.5.3 and about 60 apt-check processes within
seconds consuming 100% cpu and 100% disk io plus swapping.
this is a fork bomb triggerd by every update.
can be stopped by "killall apt-check" (if you are fast enough)

I suggest upgrading the severity of this bug to critical, as it's
basically a system crasher.
Tried to turn off auto-updates but it didn't help so i had to remove the plasma-discover packages.
I first removed the muon-discover stuff, but it turned out they were the wrong ones.

I strongly concur to the previous post. With plasma-discover installed
any apt-get update thrashes my system to a crashing halt (if I'm not
fast enough at killing the apt-check forks).

Make sure qapt-check doesn't get called repeatedly
Simplify the process that checks for system upgrades.
- Makes sure it's only run when needed.
- Doesn't recreate the QProcess instance.
Tested by soee as discussed in #kubuntu-devel.

I can confirm that on Kubuntu 15.10, Plasma 5.5.3 and Frameworks 5.18.0

because of many apt-check processes. Plasma stops responding. "killall
apt-check" doesn't help. I haven't figured anything else but restart
from console.

the same here, the issue is still affecting my system Kubuntu 15.10 with Plasma 5.5.3.

Problem here still seen on recent Kubuntu 15.10: overloads Core i7 with
lots of apt-check processes and causes heavy swap mem trashing. System
then becomes totally unresponsive. This surely is a *severe* bug.

The patch is added after 5.5.4. So it depends if kde 5.5.5 is relased or
not.
