Hi All,
Wondering whether any one can help me understand what happened. Been running filebeat for the past 6 months, and have been upgrading accordingly to our logstash. Currently on version 7.7
Never has it crashed out and it recovered after i manually restarted the service.
The host OS is Windows Server 2012 R2 - 6 CPU - 12GB RAM
The largest log file i am reading can reach 2GB in a single day. There are another 5 log files i am reading and these reach around 30MB
