Describe the bug

02.07.2024 15:03:44.124 [INFO] [com.teragrep.cfe_35.router.Router] [metrics-logger-reporter-1-thread-1] type=COUNTER, name=connections, count=5700

Expected behavior

They go back down on disconnection

How to reproduce

Just keep on spamming new connections that fail, tcpflood will send all the messages on first opened connection before the rest have finished connecting -> trying to close them before they were really even open while true; do tcpflood -t 127.0.0.1 -T relp-plain -p 4600 -m 123 -M "<14>1 2020-05-15T13:24:03.603Z performance-test-host performance-test-tag - - - hello" -c 10 -Y; done

The stats might be right as this might also be due to leaked connections that never gets closed, but issue remains

Starting the server with -DconnectionTimeout=1 -DreadTimeout=1 -DwriteTimeout=1 and spamming will leak connections even with #5
