  • 20130502T131941.847|1| - Feedback Error: A call to SSPI failed, see inner exception. 20130502T131947.647|1|Error. FeedBack ensureconnected exception. A call to SSPI failed, see inner exception – recommendation: from Sybase Control Center, confirm that the certificate used in Apple push configuration has not expired.
  • 20130516T175645.847|1|Device Token length is not 64 – recommendation: an empty token in the application connection due to a timing related error that should correct itself once the token arrives from the device. It occurs when a notification is sent to the device in the time-frame between the application connection getting activated when the token is empty and APNS token getting sent to the server from device.
  • Error: Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host – recommendation: this error is seen when the token length is empty or an expired certificate is used. This error may also be logged in cases of occasional issues with the Apple push service itself.
