Yes, I'm also getting it (on portainer v.v 2.20.3 and docker v. 26.1.3, build b72abbb) this is an annoying issue, creates thousands of unnecessary tcp connections.
after update to 2.20.2 TCP_TOTAL +500 per day. the connection keep connecting until the network reset.
check your docker server connect by tls from portainer 2.20.2 : ss -np|grep 2376
Platform and Version docker 24.0.7 and 26.1.3
same issue, 2.20.3
The same behavior:
Portainer: 2.21.0 Docker: 27.2.0
In tcpdump at "stale" connection I see portainer send TCP keepalive every 15 seconds.
And all tcp keepalive have same TCP sequence number
I had the same problem, I returned the version to 2.19.5, this problem will not occur for the time being
Before you start please confirm the following.
Problem Description
I'm using portainer and one docker (v25.0.5) instance connected via HTTPS In version 2.19.x, on average, about 12 TCP sessions are used between portainer and docker. After updating to version 2.20.2, the number of sessions reached approximately 3000 in 8 days. After updating to version 2.20.3, the number of sessions reached approximately 200 in 3 hours.
Expected Behavior
Use of a limited number of TCP sessions.
Actual Behavior
The number of TCP sessions is constantly growing
