Message: file too big for single read

Elastic Stack Logstash

Hello,

Logstash was working fine for me until this started happening. I can't start my logstash instance and I can't find some extra information on this error anywhere.

Help please

The code that is trying to read the configuration is failing to read a file that is more than 2 GB in size. If you have pointed path.config at a directory then make sure there is not a file (e.g. core) that is more than 2 GB in it.
