John it is too hard to guess from just the shared images. A full stack trace and set of logs may be more enlightening. If unzipping/opening such a thing is so incredibly slow there are two culprits I've heard of/seen in the past.
1) Anti-virus/security related software that is overly aggressive with file operations. This makes all things painful. 2) Lack of entropy such as https://issues.apache.org/jira/browse/NIFI-3313 Thanks On Wed, Mar 6, 2019 at 1:06 PM jsmith1 <mc...@hotmail.co.uk> wrote: > Hi all, > > I've been running a 3 node NiFi 1.8.0 cluster for a number of months > without > issue.
