Issue type: Healthcheck, container operation
OS Version/build: Archlinux: 5.4.52-1-lts #1 SMP Thu, 16 Jul 2020 19:35:06 +0000 x86_64 GNU/Linux
Docker version 19.03.12-ce, build 48a66213fe
AMD Ryzen 5 3600 6-Core Processor
32GB ram
Key Issue:
After my 23 containers have been up for ~5-8hrs, ALL health checks begin to fail - but the containers continue to operate as usual. CPU utilization is consistently < 10%. Snapshot of stats are below.
When I dig into the rationale for the healthcheck fail, I find: Health check exceeded timeout (30s)
if I enter the container (e.g., docker exec -it container /bin/bash), all looks fine, but then if I try to EXIT, it HANGS. same on all containers that have a healthcheck (e.g., pihole)… Containers without a healthcheck exit just fine. I am stuck. does anybody have any ideas? Ive been running essentially these same containers for years, on an even less capable machine. I’ve also tried deleting all of docker stores, and recreating all containers. same problem. thank you so much
