gevent connection过多问题

今天redis重启，由于重启很慢导致connection很多

[admin@server13 ~]$ netstat -an|grep ':6389' |grep "ESTABLISHED" |awk '{print $5}'|awk -F: '{print $1}' |sort |uniq -c | sort -rn
   1786 192.168.172.14
   1213 192.168.172.8
   1161 192.168.172.10
    640 192.168.172.4
    524 192.168.172.9
      4 192.168.172.7
      2 192.168.172.3
      1 192.168.172.5
[admin@server13 ~]$ netstat -an|grep ':6389'| wc -l
5328
[admin@server13 ~]$ netstat -an|grep ':6389'| wc -l
4195
[admin@server13 ~]$ netstat -an|grep ':6389'| wc -l
4305
[admin@server13 ~]$ netstat -an|grep ':6389'| wc -l

[admin@server10 ~]$ netstat -an|grep ':3306' |awk '{print $5}'|awk -F: '{print $1}' |sort |uniq -c | sort -rn
