Investigate this WorkerLostError

• use flower to get more data ? celery --broker=amqp://login:password@resif-dev1.u-ga.fr:5672/waveqc flower
• Remove the Request class as it does not work
• run super() methods on on_failure() and after_return() methods ?
• set prefetch = 1 ?
• set concurrency = 1 ? Or stick to the number of cpu available ?
• use solo pool ?
• is swap available on pods ?
• use --max-memory-per-child ?
• close mseed files when processed ?
