repeat "runFullImpl: failed to generate timestamp token" after completion

[euzenlee]

After completion, the following message keeps repeating and the program cannot be exited :

runFullImpl: failed to generate timestamp token - skipping one second runFullImpl: failed to generate timestamp token - skipping one second

Repeated the execution a few times and found that it was not processed to completion, with about 20 or 30 seconds remaining.
