The reason is unknown but it happened in https://gitlab.inria.fr/batsim/batsim/builds/9158. The crash is deterministic.

mpoquet commented 7 years ago

Might be related to the callback function after process exit.

MSG_process_on_exit(execute_profile_cleanup, cleanup_data);

@adfaure: if you are looking for some funny debugging sessions, this bug can help you :D

Is this still happening?

mpoquet commented 5 years ago

Currently (548cd4b):

Kills are broken in some scenarios regardless of Redis (https://framagit.org/batsim/batsim/-/jobs/246085)
Memory deallocation on kill is not done. I'm waiting for a small s4u update to enable killing parallel tasks to completely get rid of MSG. =/

Closing this issue as this should be fixed AND because redis is about to vanish.
