Thanks. That has a stack trace to investigate:

```

Title:
  Apport apparently hung while gathering information for another crash.
  CPU time was logged at around 20hrs+ when I found out.

Status in apport package in Ubuntu:
  New

Bug description:
  This machine has been generating a lot of crashes (sorry for all of
  the uploads...) including apport its self, but hopefully the
  information collected here is able to narrow down what's going on.

  
  $ lsb_release -rd
  Description:    Ubuntu 20.04.6 LTS
  Release:        20.04

  $ apt-cache policy apport
  apport:

  Expected to happen: apport does its work in a timely manner then exits.

  What appeared to happen: apport had hung/entered a loop which at the
  time I found it, with above twenty hours of CPU time. Unfortunately I
  can't offer any other information about the circumstances or why
  apport had entered this state besides what was captured by apport on
  its self.
