I am running a rails app and using redis for jbulder's cache and sidekiq queue. I use sidekiq to send emails asyncly, everytime when I try to send mass emails, say 20k emails in background using sidekiq, after a while, all the background jobs in sidekiq queue are cleared, left 0 jobs in queue.
I filed an issue on sidekiq github page(link), the author said it could be something or someone flushing my redis. There's no one flush redis manually and I wonder how can I find when and how redis gets flushed.
I've checked redis log file with nothing strange.
