Tens of thousands of temporary directories?

[zb140]

I'm running Flagsmith in a docker container and it's largely working very well for me, but something in the container is creating a new directory under /tmp about once per second. They have names like /tmp/tmp8nr5g5hq and are (as far as I can tell) always empty. After a day or so it hits the hardlink limit and the container stops responding till I go in and clean them out, which "resets" the "timer". I've tried looking for whatever is creating the directories to see if there's some way to stop it, but I haven't been able to find it yet. Has anyone else seen this?

In case anyone stumbles across this, it's being caused by the healthcheck. With PROMETHEUS_ENABLED=true, this line creates 2 temp dirs per healthcheck cycle. With PROMETHEUS_ENABLED=false, it creates only 1 temp dir per healtcheck cycle. I assume setting PROMETHEUS_MULTIPROC_DIR will stop it from making any temp dirs, but the container won't start if I set it to a non-existent dir, and I couldn't find a way I liked to use an existing one without mapping in a volume. So I disabled the healtcheck, at least for now.
