Expected behavior

Expecting 6 cache files size 25m.

Actual behavior

Currently 5 cache files size 20m, parameters "cache-max-size" and "cache-max-file" not working.

Steps to reproduce the behavior

It some problem with caching docker logs from containers. When we use:
“gelf-address”: “tcp://xxxxxxxx”,
“cache-max-size”: “25m”,
“cache-max-file”: “6”
Cache parameters doesn’t work, every time we have 5 files, 20m size.
