[Bug 1979942] [NEW] mpm_event fails to restart all childs gracefully

 

Public bug reported:

Reported on the ML [1] and seems to be a valid and real bug for some
active releases.

It is in 2.4.49 and thereby fixed in Jammy and later.
Introduced in 2.3.34 so it wasn't present in Bionic yet.

Upstream bug [2]

It first sounded (by the words) a bit like this old bug [3], but it is
an entirely new thing.

Since it is fixed upstream we know the change which looks kind of small
and reasonable [4].

Maybe someone could evaluate how well (or not) applicable that would be
to Focal/Impish?

@Mike - if you read this later, to SRU it we will need a testcase and
the upstream bug isn't very helpful. If you would be able to add a step
by step description how to trigger the case that would be very helpful.

States from here:
- Triaged for now, action is to eval the applicability of the change
- Then if repro steps exists let us look at an SRU, if not -> incomplete
