[Bug on N9] AGTL sometimes hangs repetively for no reason

[caco3]

Sometimes, AGTL works well for a long time. But sometimes it hangs every few seconds for no visible reason.
Looking at the terminal log, it doesn’t show any error.

If I then try to terminate it with CTRL-C, I get this output (trace):
