Which filebeat version are you using?
What is your OS?
How much memory does filebeat have available?

steffens · October 10, 2017, 11:54am

How long are the lines in your log files?

Kyle-Wilson1 · October 10, 2017, 2:50pm

version: 5.6.X(and i extend some other functions in output module)

AWS server:
Linux pf-us-app-4.or.aws.tap4fun.com 3.2.0-60-virtual #91-Ubuntu SMP Wed Feb 19 04:13:28 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

memory usage

i start filebeat at about 6:30~7:30 ,and the problem happens at that time.

Kyle-Wilson1 · October 10, 2017, 2:57pm

each line is about 1000 byte, not exact . some is short ,other is too long maybe.

Kyle-Wilson1 · October 10, 2017, 2:59pm

usual time

Kyle-Wilson1 · October 12, 2017, 7:25am

hello,
the issue occur again, could you help me with it please ?
it looks like memory leak ,the memory usage is so strange.

range 6:22~6:30 , it crashes.

ruflin · October 13, 2017, 7:40am

Could you share the output part of your config file and share the full logs from filebeat? How many log files are in the platform directory?
