The problem:
I have a FreeBSD 14 machine and a FreeBSD 13-stable machine, both running the same jails just to test the workings.

The jails that are running are a salt master, a haproxy  jail, 2 webservers, 2 varnish servers, 2 php jails one for php8.0 and one with 8.1. All the jails are connected to bridge0 and all the jails use vnet.

I believe this worked on an older 14-HEAD machine, but i did not do a lot with it back then, and when i started testing again and after updating the OS i noticed that one of the varnish jails lost it's network connection after running for a few hours. I thought it was just something on HEAD so never really looked at it. But later on when i start using the jails again and testing a test wordpress site i noticed that with a simple load test my haproxy jail within one minute looses it's network connection. I see nothing in the logs, on the host and on the jail.
From the jail i can not ping the other jails or the IP adres of the bridge. I can however ping the jails own IP adres. From the host i can also not ping the haproxy jail IP adres. If i start a tcpdump on the epaira interface from the haproxy jail i do see the packets arrive but not in the jail.

I used ZFS to send all the jails to a 13-STABLE machine and copied over the jail.conf file as well as the pf.conf file and i saw the same behavior.

Then i tried to use 13.0-RELEASE-p7 and on that machine i do not see this happening. There i can stress test the machine for 10 minutes without a problem but on 14-HEAD and 13-STABLE within a minute the jail's network connection fails and only a restart of the jail brings it back online to exhibit the same behavior if i start a simple load test which it should handle nicely.

One of the jail hosts is running under VMWARE and the other is running under Ubuntu with KVM. The 13.0-RELEASE-p7 jail host is running under Ubuntu with KVM

Thank you for your time.

Johan
