atop shows the disk as being all red with IO - 100% utilization. There are a lot of flowfiles currently trying to run through, but I can't monitor it because....UI wont' load.

Joe,

I’d recommend taking a look at garbage collection. It is far more likely the 
culprit than disk I/O.

Thanks

I'm getting "java.net.SocketTimeoutException: timeout" from the user interface 
of NiFi when load is heavy.  This is 1.18.0 running on a 3 node cluster.  Disk IO is high 
and when that happens, I can't get into the UI to stop any of the processors.
Any ideas?

I have put the flowfile repository and content repository on different disks on 
the 3 nodes, but disk usage is still so high that I can't get in.
Thank you!
