What are the causes of errors on Redis socket (Yii2)?

Question

Yii

Tell me what could be the problem with Redis and Yii2. As far as I understand, at some points Redis does not have time to process requests and connections begin to grow sharply. I am getting these errors:

[error][yii\redis\SocketException] yii\redis\SocketException: Failed to read from socket.
Redis command was: GET 4409ee710349bf94ce421efc4bd946a2 in /var/www/prj/vendor/yiisoft/yii2-redis/src/Connection.php:804

[error][application] Failed to write to socket. 0 of 37 bytes written.
Redis command was: *2
$3
GET
$17

[error][yii\db\Exception] yii\db\Exception: Failed to open DB connection. in
/var/www/prj/vendor/yiisoft/yii2-redis/src/Connection.php:643

There are no errors in the radish logs.

Try setting a connection timeout and the number of connection retries.
