I presume you are using Elasticsearch output. This error means that filebeat is sending a bulk request with a body that is too big for Elasticsearch to handle (i.e. you have long log messages). You could try setting a lower bulk_max_size in the output configuration (default is 50)
Hi thiago, yes, the output is ES, I'll try to change that value to 100 maybe?, my concern was about the comment
that says NOT to change that value , and do not know why.
The setting that I am referring to is bulk_max_size which is different from bulk_queue_size (which has the warning). Also you should lower it and not increase, because the issue is related to how much data filebeat is trying to push into ES.
