IndexUpdater info

(from github.com/freestyle68)
Hi,

Fess last commit (yesterday), Java 10 and elasticsearch 6.4.1.

It happens the performance of a smb crawling are progressively degrading, after 130000 docs becoming very slow. In this case I see similar logs on fess-crawler.log and the crawling stop with low CPU usage and low IO throughput, so this is not a hardware resource problem. I have tuned garbage collector but with litte success.

What this messages mean?

Thank you

You need to set proper settings(# of shards, heap size,…) for your environment.
