fatal: deadlock detected

[milindphirake]

I implemented the push notifications and GCM notifications using this gem working great.

@ileitch

But i came across one strange issue. Sometimes my rails server goes into deadlock state.

Any Help on this will be great

I got the following log.

It cames when there is noting to push and we call "Rapns.push"

Log= >

Rapns::Notification Load (0.6ms) SELECT rapns_notifications.* FROM rapns_notifications WHERE (delivered = 0 AND failed = 0 AND (deliver_after IS NULL OR deliver_after < '2014-01-22 17:30:48')) AND (app_id IN (1,2,3,4))
=> {}
