AStar does not release nodes for longer than Deallocation Time Offset

[ FlexSim 24.0.7 ]

Hi,

AStar does not release nodes for longer than Deallocation Time Offset.

In the attached model, TaskExecuter2 is leaving the node in front of TaskExecuter3 at 5 seconds, so it should release that node after DellocationTimeOffset (2 seconds) has passed, but that doesn't seem to be the case.

Is this the same issue as the post linked below?

Are there any workarounds?

Thanks in advance.

Hello @Shinya O,
No this is not the same issue. It was determined that model was not repeatable.
I am not seeing the issue you are. I am using 24.0.8. Can you see if upgrading to the latest bug fix resolves your issue?
Edit: dev has been notified of this issue.

I can see the issue in 24.0.8.

I emailed @Jordan Johnson and was informed that this issue was a bug in AStar logic, but I forgot to report it here.

This issue has been fixed in 24.0.9 as stated in the release notes.

Fixed an issue with allocation release time when travelers become blocked.
