Hi,

I use logstash to parse application logs with multiline being used to split the logs into events based on regex. This works under normal load in logstash. However in certain times when the input from filebeat to logstash increases in load, this mutiline split fails in splitting into meaningful events. Anyone else faced similar issue or have a solution for the same?
