Did you get a patch for this issue? I have to admit I can't follow the logic, when the AGED event breaks what's the fallout?

ahogan had replied with a patch and then it was mysteriously removed. by whom I do not know! We are testing using the AVNU violett test suite and we are getting some gPTP errors.
The PortAnnounceInformation State Machine does not seem to check currentTime=syncReceiptTimeoutTime and enter the AGED state.
The test specification for gPTP.com.c.3.1b can be found in the following Avnu document:
https://groups.avnu.org/wg/Avnu_Members/document/3133
The issue can be found where the TS is sending Sync/FollowUp every 500ms which is definitely a timeout situation. However the device does not start sending Announce and Sync/FollowUp as it should.
