cent7 환경에서 squid 연결이 안되서 현상이 가끔 나오고
netstat 로 확인시 socket_close 로 상태로 되면서 접속이 안됨.
squid 재시작 하면 정상 작동함.
찾은 원인은 swap 디스트를 기존은 5기가 이었는데 이것을 다 사용해서 문제가 발생함
swap disk 공간을 20기가를 추가해서 총 25기로 변경함

In the cent7 environment, squid cannot be connected, so the phenomenon sometimes occurs
When checking with netstat, the status is set to socket_close and connection is not possible.
Restarting squid works fine.
The cause I found was that the existing swap disk was 5 gigabytes, but the problem occurred because it was used up.
Changed the swap disk space by adding 20 gigabytes to a total of 25 gigabytes.
