[Aerogear-users] Push Problem on 1.1.1.Final Push

Hello, We are currently running Aerogear Push 1.1.1.Final on a Jboss EAP 6.4 since a year now without any issues. However, a problem that we had prior 1.1.0 release (http://lists.jboss.org/pipermail/aerogear-users/2016-June/000821.html) is coming back. When we are making a push we got this error (sometimes) : 08:29:08,265 WARNING [org.jboss.aerogear.unifiedpush.message.sender.APNsPushNotificationSender] (MonitoringThread-1) Internal cache size exceeded, new size is: 150 08:29:08,265 SEVERE [org.jboss.aerogear.unifiedpush.message.sender.APNsPushNotificationSender] (MonitoringThread-1) Error sending payload to APNs server: com.notnoop.exceptions.ApnsDeliveryErrorException: Failed to deliver notification with error code 8 at com.notnoop.apns.internal.ApnsConnectionImpl$2.run(ApnsConnectionImpl.java:199) [apns-1.0.0.Beta6.jar:] at java.lang.Thread.run(Thread.java:745) [rt.jar:1.7.0_75] Do you know where the problem might come from ? Best Regards, Romain Javornik
