Sidekiq start and finihes (ERR wrong number of arguments for 'srem' command)

I have a GitLab CE installed in a ubuntu 12.04 openvz (proxmox) container. The system is now a GitLab 7.13.4 7c3e8bc version wich has been updated from order ones. The installation and update are made from source.

I see Sidekiq starts, but it finishes/crashes.

I see un logs/sidekiq.log

2015-08-08T18:21:56.228Z 6292 TID--92qkkq WARN: Sidekiq died due to the following error, cannot recover, process exiting

If i restart sidekiq with sudo -u git -H RAILS_ENV=production bin/background_jobs start it starts normally as in the init script, an then finishes with the same logs.

I do not know how to continue for obtaining more logs and solve the problem or report it.

thanks in advance,

I solved the problem updating redis. The host is an ubuntu precise system which has the 2:2.2.12-1build1 version in the default repository…

I used this independient version of redis.
