[aerogear-dev] Long delay from first to last push message received on iOS devices

Hi, we're experiencing a delay when sending push messages to iOS devices. Our biggest push application have 32690 iOS devices registered and a smaller amount of android devices. We see that the delay is up to 20 minutes from first to last on iOS everytime. We are using version 1.1.0-beta.4, and have upgraded from 1.0.2. Table ups_db_changelog have 135 rows Running wildfly 8.1.0 Final We had the same problem with 1.0.2 but then we could see the delay in the log output, now according to the logs it takes around 10 seconds. (see fine.log), we also see this in the network traffic out from the server. The only error we're seeing in the logs is on MonitoringThread-1 (MonitoringThread-1) Exception in thread "MonitoringThread-1" java.lang.NullPointerException (MonitoringThread-1) at org.jboss.aerogear.unifiedpush.message.sender.APNsPushNotificationSender$2.messageSendFailed(APNsPushNotificationSender.java:232) (MonitoringThread-1) at com.notnoop.apns.internal.ApnsConnectionImpl$2.run(ApnsConnectionImpl.java:199) (MonitoringThread-1) at java.lang.Thread.run(Thread.java:745) Do you have any ideas on why this delay is happening, and how to solve it?
