Random timeout connection on v 3.0.2 and predis

[Jose Ramon]

Hello, i'm getting Connection timed out error on my redis server with the command "hincrby key field 1"

The connection is from same machine, my redis version is 3.0.2.

The connection timeout is set at 60 seconds.

Some stats:

Database size 15mb

clients connected: 175

command per minute: 17000

HINCRBY per minute: 6500

My client is predis 1.0.3

How can solve the issue?

Thanks

Does your client make a new connection to the Redis server for each command?  I.e., connect to Redis, issue 'hincrby KEY FIELD 1', get the reply, and disconnect from Redis.  If so, perhaps the timeouts are on the connection rather than the 'hincrby' command itself.

Have you enabled the Redis slow log and checked it after one of these timeout events?  Does it list a command that's slow during the events?  What do your server performance graphs say is happening with the Redis machine's cpu, memory, disk, and network during an event?
