When I monitor the Redis using monitor command I observe there are lots of info command is being executed. Is this executed by Redis server itself or by the client applications?

The problem is, when I check the output of the client list command on the server, there are lots of open connection objects on info command which is causing the server to crash with below error.

  • Seems like you are opening multiple Unix socket connections until you reach Redis limit which is 128 by default. – Ariel Mar 09 '20 at 08:45

    in the client application, I am opening and closing the connection whenever it is required, but does every open connection makes a ```info``` call on the Redis? – vikas kv Mar 09 '20 at 09:24
