Error with listener 7080

[ltynk]

Hi,
I encountered this issue for the second time. Unfortunately I was not able to check what occupied port before server was rebooted.

Basically port 7080 gets occupied and this results in not loading any vhost. SSH working, all thing, but nothing loads. Logs shows this:

2020-09-24 03:56:31.827112 [ERROR] HttpListener::start(): Can't listen at address adminListener: Address already in use!
2020-09-24 03:56:31.827769 [ERROR] HttpServer::addListener(adminListener) failed to create new listener
2020-09-24 03:56:31.827784 [ERROR] [config:admin:listener:adminListener] failed to start listener on address *:7080!
2020-09-24 03:56:31.827793 [ERROR] [config:admin:listener] No listener is available for admin virtual host!
2020-09-24 03:56:31.827825 [ERROR] Fatal error in configuration, exit!

Strange is that it is doing on one particular server. Other with same config are fine. I found out that at the same time there is certbot working. Could it be issue? Any idea how to prevent it?

Hi,

Let's encrypt probably not the issue. Better get the result next time with the following command so you can see which process occupied the admin port,

netstat -antupl | grep 7080

Best

Hi, it happened again! I checked port before reboot (solved it as before) but nothing. Empty output and you can see it without grep:

Any other idea? OLS was meanwhile upgraded to 1.6.15. And it has to be something weird because as I mentioned it's just one server with no extra configuration.
