It's completely impossible to help without any details. What's your configuration, for example?

Have patience. If patience is scarce there are paid support subscriptions. Regardless of what channel you use to get help, you _must_ realize that it's in your best interest to ask as clear of a question as possible.

Presumably the sincedb file (whose path is in the log) indicates that Logstash already has processed the file in question. In that case you have to delete the sincedb file to have Logstash process the file again.

I have seen people do this, I am sure if you run a search on the net for the topic you will find something.

Was your intention with this to disable sincedb? It doesn't. Use /dev/null if you want to disable sincedb.
