2 years ago Hi @binarious , Thanks for creating the issue. Would it be possible to share a small reproducer. I have tried doing isolated load testing on aardvark server only by running it without netavark and it never fails but i am assuming something might be re-setting connection at netavark's end not sure but it could be something similar to https://github.com/containers/netavark/issues/210.
#!/bin/bash
for (( c=1; c<=100; c++ ))
do
dig -p 5533 @<my-interface-ip> testdbctr
doneI am still trying for a reproducer so will update once i am able to reproduce this issue.

I've setup a nextcloud deployment with podman in combination with docker-compose. It's working fine mostly and dns is also generally working. But around every 30s I see connection issues between containers. I've created a test script which queries the database every second and I often see connection errors (
SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Try again).journalctlshows the following output at these times:Any ideas?
