Kue - Error: Auth error: ERR max number of clients reached

Question

I am getting an redis connection error when depolyed in APP Fog. I don't know if KUE is generating too many connections.

Here is stack

/mnt/var/vcap.local/dea/apps/kue-0-543205581cf47e8551d042ab06df92e1/app/node_mod
ules/redis/index.js:516
throw callback_err;

The redis server log shows it made 5 client connections. is there a way to reduce the no of connections

Thanks
