Hi,
We have separate filebeat per running container setup at the moment.
Filebeat writing direct to elastic search.
After upgrading from 5.6.14 to 6.4.2 filebeat version it started to crash after some time of up and running with
fatal error: concurrent map iteration and map write
goroutine 60 [running]:
