SQS batch not working.

[Tumeloq]

I cannot receive batch massages always getting single message at time. Sample request
Action=ReceiveMessage&Version=2012-11-05&AttributeName.1=All&MessageAttributeName.1=All&MaxNumberOfMessages=10&WaitTimeSeconds=20.

I debugged the code. gosqs.go

if app.SyncQueues.Queues[queueName].IsFIFO {
// If we got messages here it means we have not processed it yet, so get next
if app.SyncQueues.Queues[queueName].IsLocked(msg.GroupID) {
continue
}
// Otherwise lock messages for group ID
app.SyncQueues.Queues[queueName].LockGroup(msg.GroupID)
}
This runs in loop and only the first message will returned. The second iteration will execute.
if app.SyncQueues.Queues[queueName].IsLocked(msg.GroupID) {
continue
}
