[systemd-devel] log_assert_failed_realm crash in systemd journal-file

[Aditya Tayade]

Hi,

I am getting below crash in our CI environment with systemd v244-stable
which looks similar to issue #14943
<https://github.com/systemd/systemd/issues/14943>. So could you please
confirm if it is the same issue and whether the PR:
https://github.com/systemd/systemd/pull/15557 (already merged in v246) will
fix this? If yes then we need back port of these PR to v244-stable as well
and if not then could you please help to understand what can be cause of
this?:
