A solution to memory leak in server

The story background

A long time ago, I used my cousin's student ID to collect an alicloud low configuration host , I didn't renew any of them until they expired , Fortunately, the renewal was successful before the server data was cleared , But when I log in to the server, I find that the card is not smooth , And found in the server docker Unable to run .

Incident investigation

When running on the server docker I will make the following mistakes ：

fatal error: runtime: out of memory It is obvious that the server memory leaks , It burst .

Solution

It is found that the cause is due to a gitlab Process causes , kill gitlab The related process services are used normally, but it is found that the server services cannot be accessed normally in the browser , But the service address ( website ) It's ok ping through , Use netstat -anp | grep :80 Find out nginx I didn't get up .

• Use nginx -s reload An error is as follows

# nginx -s quit
nginx: [error] open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file or directory)

• Solution
