Running short of concurrent connections.

[3245]

Hello
we have below message in our litespeed, all of them is for one user:

root@dl [~]# netstat -an | grep 80 | grep ESTA | wc
957 5742 85173

server is for dowonload server, i think usage is high, how i can limit usage?

when i run below command:

netstat -anp |grep 'tcp\|udp' | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n

i see some of ips have 80 connection or 70 connection, it is much, correct?
that is shouldnot more than 20, correct? how i can config?


Thanks!
