Redis socket + Huge Error Log + No such file or directory

We are using W3 Total Cache.
The cache backend is Redis via socket.

We found that if the Redis is stopped (for any reason), it will generate a huge Apache error log (in terms of GB in a few hour).

If possible, for Redis with socket, may I suggest W3 Total Cache to check the existence of socket before connection?

Thank you.
