Hello lincvz, Sorry about the delay. I have been busy with other stuff and did not have time to follow up on this bug. Here is the lay of the land right now:
1) Unfortunately, it is unlikely that we will be able to get the SRU team to accept an upload that reintroduces an issue. This means that removing the patch that causes the infinite loop is something that we would rather not do, because another problem will reappear. 2) The ideal course of action here would be to investigate whether it would be possible to backport the patch at https://github.com/openldap/openldap/commit/735e1ab14bb055344b4e767a216aa410aa7d1503 and make it fully work. This is probably a non-trivial task, as Ryan himself said. I am still looking into a possible solution for this, but I cannot guarantee anything for now, I'm sorry (I'm very busy with other stuff, including updating OpenLDAP in Impish to 2.5!) Given that I have provided a PPA with a package that fixes the issue for you, I would say that for now you are better off using it. Last, but not least: if you feel like giving it a try and trying to backport https://github.com/openldap/openldap/commit/735e1ab14bb055344b4e767a216aa410aa7d1503 to the openldap version that's in Bionic, that would be awesome. We can review whatever you have and guide you through the SRU process.

To recover, slapd needs to restart. No related information is reported in log file. All same issues in OpenLDAP upstream project are old and fixed. So maybe this issue affects only Ubuntu package. It occurs randomly, so I have no steps to reproduce.
