Some background:

Here is how my code sends the APNS notification:

` String payload = null;
try {
ApnsService service = getService(tocCode);

        if (service != null) {

            payload = APNS.newPayload()
                    .sound("default")
                    .alertTitle(dataMap.get("title"))
                    .customFields(dataMap)
                    .alertBody(dataMap.get("message"))
                    .build();

            final Collection<? extends ApnsNotification> push = service.push(deviceids, payload);

            deleteInactiveDevices(service);

        } else {
            logger.error("Could not initialize APNS service );
        }`

Sometimes Push notification are going through and are being recived other times they are not and the above error is thrown . Can anyone please help with this ?
