exit code 15 🔗 link

Hello.

Recently our hobbit service is aborting, with the following message:

Worker process died with exit code 15, terminating

which can be found on enadis.log, larrd-data.log and larrd-status.log.
Could someone please tell me what does that mean? It probably is the hobbitd 
module crashing, but why?

Best,
Eduardo Greif
