Must delete files in message queue to start logstash

@panaman so, once the "first seqNum=0 is different than minSeqNum=xxxx" exception happen on startup, it will always happen, as you figured, unless you wipe/moved the queue data dir. What I am trying to understand is exactly what happened before that first restart exception occurred.

  • Did you first get a too many open files error which crashed logstash and then upon restart the "first seqNum=0 is different than minSeqNum=xxxx" exception occurred?

  • Can you share or describe you config, including input(s) and output(s) prior to using Kafka and then with Kafka?
