sonewconn: pcb 0xfffff8004791b000

Today while I was installing system patches on 25.07.1 and Haproxy + Suricata updates, my OpenVPN was disconnected. I have also second server so I had to use this one. I found this in system log:
sonewconn: pcb 0xfffff8004791b000 (local:/var/etc/openvpn/server1/sock): Listen queue overflow: 2 already in queue awaiting acceptance (2 occurrences), euid 0, rgid 0, jail 0

There is also higher CPU usage then usualy. How to debug this issue? It never happen before. My OPenVPN is unable to start. Am I safe to reboot? It is Netgate 6100.

Try this :
Use the console or SSH access.
Open 8.
Check if OpenVPN is (already) running / if there is a borked instance in memory:

ps aux | grep 'openvpn'

If you find any, kill them. Use the kill command to kill a process using its proces ID number.

Now you can restart OpenVPN again - use the GUI for this.

Hello, I asked local guy to reboot device, which allowed me to connect again. It is remote site unfortunately... but it interest me, that something like that happen. I am using pFsense at least 6 years actively without any issue like this.

Before I tried to kill openvpn instance from GUI but it didnt worked.

Hmm, so after the reboot it came back up as expected?
