[Bug 2066990] Re: high memory consumption in Ubuntu Noble

[Adrien Nader]

NB: we can only SRU that to Noble if it first goes in a development
version of Ubuntu which will only be possible when development for 25.04
begins.

** Summary changed:

- high memory consumption in Ubuntu Noble
+ openssl fails with out of memory messages while trying to load the FIPS provider in a non-FIPS container on a FIPS host

Title:
  openssl fails with out of memory messages while trying to load the
  FIPS provider in a non-FIPS container on a FIPS host

Status in ca-certificates package in Ubuntu:
  Confirmed
Status in openssl package in Ubuntu:
  Confirmed

Bug description:
  I wanted to try the new Ubuntu 24.04 Noble Numbat based .NET docker
  image and updated the base docker image in our CI pipeline to
  mcr.microsoft.com/dotnet/sdk:8.0-noble. However, it results in an out-
  of-memory exception. Based on my investigation, the exception occurs
  specifically when the update-ca-certificates command is executed. I
  can also repro the issue with ubuntu:noble image which means it's not
  specific to .NET docker images. It works fine with Jammy, by the way.
  The problem likely lies with the Noble base image rather than the .NET
  image. I'm not sure what changes were made between Jammy and Noble,
  but it appears that updating certificates consumes a lot of memory in
  Noble. I adjusted some memory settings in our GitLab runner, but it
  didn't resolve the issue. I attached all Gitlab Runner shell logs for
  .NET 8 Jammy, .NET 8 Noble and Ubuntu Noble images.
