389ds docker container crashes: Unable to find PID of ns-slapd process

Question

I'm trying to use the 389ds directory server. Unfortunately, it crashes about 30 seconds after startup. Here is the MWE:

docker run 389ds/dirsrv:2.1

The error message I get is:

Unable to find pid (/data/run/slapd-localhost.pid) of ns-slapd process

After having tried several debugging attempts, I am out of ideas now. Does anyone have an idea why this crashes or what I could try to investigate the problem effectively?

Debugging attempts

While the container was still running, I used docker exec to enter a shell in the container and used ps to check whether the ns-slapd was still running. It was running in the beginning but seemed to stop or crash at some point.

However, I was not able to find the source of the problem.

It seems strange to me that the very same container image works like a charm on the computer of a friend of mine.

Answer 1

we had the same issue with Docker 20.10.8 on Ubuntu 22.04. Upgrading to 20.10.17 solved the issue. No idea why
