Icecast - Oct 2020 - meaning of global connections and global client_connections in error log

hallo 

firstly sorry for posting to wrong thread


i want to ask if somebody could explain meaning of log records below

DBUG stats/modify_node_event update global connections (686)
DBUG stats/modify_node_event update global client_connections (685)

number in parentheeses is increasing in every log line
what is menaing of this number?
because this number goes over 59669
and it seems that after that icecast2 server is not responding anymore
so i tryied to restart it with 

systemctl restart icecast2

but with no success

kill -9 is working

and that number is start increasing from zero

thanks for any advice

regards
tyctor
