No worries. The sincedb is not really damaged, it is reporting the truth exactly.

I go into a lot of detail about the sincedb and how file read positions are tracked in [this Discuss thread](https://discuss.elastic.co/t/logstash-7-w7-issue-input-file-issue-with-sincedb-reads-file-only-once/176571). Read my posts if you want a better understanding of a complex topic that seems simple on the surface.

Good Luck.
