PTV Developer: Track zombies
Posted: Wed Feb 23, 2022 3:00 pm
We do run a lot of interfaces 24/7 and have seen the strangest things in TCP/IP communication. In connection with PTV Developer I have the following questions:
What happens when we do not delete map matching tracks with deleteMatchedTrack?
The usual call sequence is like that:
1st: createMatchedTrack
2nd: getMatchedTrack polling for the ID from the response of the first call till the status is SUCCEEDED or FAILED and not longer RUNNING
3rd: deleteMatchedTrack for the ID from the response of the first call
Given there is an issue, that interrupts that sequence, then there will be track zombies that no one will cleanup.
