This is a valid issue, but are we certain it's the same one? The reporter talked about sched_yield and their backtraces included several threads of back_monitor waiting on some kind of lock. >https://bugs.openldap.org/show_bug.cgi?id=8650#c12 explains that it's >https://github.com/openldap/openldap/commit/7b5181da8cdd47a13041f9ee36fa9590a0fa6e48 >that is responsible for the issue. > >https://github.com/openldap/openldap/commit/4c1ab16ade18a253dd81df7e6eced4d920ac6a8e >reverted that commit, but that one did not make it into bionic. Indeed. :( I didn't notice this went unfixed in an LTS, I'm sorry for missing that. >So cherry picking >https://github.com/openldap/openldap/commit/4c1ab16ade18a253dd81df7e6eced4d920ac6a8e >should fix it. In this version it's a Debian patch, so probably just remove the offending patch from d/patches, rather than import the revert?

I'm not confident I can backport that correctly, so I'd feel safer just doing the revert. However, sssd should also be tested, to ensure the version in bionic isn't affected by ITS#9210 (https://bugs.openldap.org/show_bug.cgi?id=9210).
