Redis Singleton Instace via create factory fails with set Promotion:Lock

Trying to use singleton redis client with through kue under which I am getting this issue:-
Am I doing any thing wrong :-

I just keep getting these two lines in my log and nothing happens until time out.

ioredis:redis write command[127.0.0.1:6379]: 0 -> set([ 'promotion:lock', 'LB+WEMyOEeiOhNtmySv7aw==', 'PX', '2000', 'NX' ]) +999ms

ioredis:redis write command[127.0.0.1:6379]: 0 -> set([ 'activeJobsTTL:lock', 'LCAyUMyOEeiOhNtmySv7aw==', 'PX', '2000', 'NX' ]) +3ms
F

Please advise. What is happening here and is it possible to use a singleton Redis Client along with Kue.

Start by examining how Kue creates and shares its ioredis client, then reproduce the timeout with the logged SET commands for promotion:lock and activeJobsTTL:lock. Determine whether a singleton Redis client is supported and document or fix the locking behavior so the queue proceeds without timing out.
