I have a problem whereby one device on my BES (22.214.171.124) keeps on having issues with delivering messages. The problem is intermittent and is characterized by a buildup of pending data packets. These do sometimes appear to be going through, but very slowly. The only way I can get the packets delivered is to either remove and replace the battery on the 8900 device (latest software), or go in to the host routing table and re-register the device on the RIM network. Do people think that this is just a problem with the device - I don't have any problems with my other devices on the BES, albeit, they are on O2 rather than my one T-Mobile device. Is there anything in the logs which would indicate that a device is experiencing problems connecting to the RIM network?
