> Our team recently upgraded to 1.13.2 from 1.11.4.  The performance improvements caused a number of servers which see quite a bit of data to perform better.  However, we began experiencing "frozen NiFi's".  NiFi's that appear fine, but will not process any data. We determined the file I/O improvements from the 1.11.4 to 1.13.2 release were significant enough for us, that we increased the amount of data passing through them to go from the 50% archive to exceeding the 52% archive backpressure percentage prior to the archive job completing. 
> This locked-up all our NiFi's causing us to revert.
> How did we figure this out?
> We came across a mailing list email outlining the _*undocumented*_ NiFi Property *nifi.content.repository.archive.backpressure.percentage* causing the issue.
> This is a repeatable issue.  Something more should be done to warn the user on the UI that this has happened.  Until then.  Here is a ticket outlining all of the missing properties in the [Sys Admin Guide|https://nifi.apache.org/docs/nifi-docs/html/administration-guide.html] as compared to the real properties defined in [NiFiProperties.java|https://github.com/apache/nifi/blob/main/nifi-commons/nifi-properties/src/main/java/org/apache/nifi/util/NiFiProperties.java].
