Java deadlock when saving an BackendlessEntity

Hi, I’m getting this fault:

FAULT = ‘Server.Processing’ [java.lang.RuntimeException: java.lang.RuntimeException: com.mysql.jdbc.exceptions.jdbc4.MySQLTransactionRollbackException: Deadlock found when trying to get lock; try restarting transaction] <java.lang.RuntimeException: java.lang.RuntimeException: com.mysql.jdbc.exceptions.jdbc4.MySQLTransactionRollbackException: Deadlock found when trying to get lock; try restarting transaction>

when I try to save a custom entity (I’m saving integers to variables). Any idea?

I’m using this iOS Swift code structure:

Backendless.sharedInstance().persistenceService.of(Vote.ofClass()).save(vote, response: { (object : AnyObject!) -> Void in

// some editing

        Backendless.sharedInstance().persistenceService.of(Photograph.ofClass()).save(photograph) // this one faults















        Backendless.sharedInstance().persistenceService.of(Challenge.ofClass()).save(challenge) // this one succeeds












        }, error: { (fault : Fault!) -> Void in

// nothing here

    })

Miroslav,
