@Richard_Cordovano Just FYI it seems to have happened again. 40% through a 3.3Tb dataset and it slowed down to an unusable speed. This post wont let me link the most recent thread dump so I created a new post here with the latest thread dump link. Slow ingest dump - version 4.18 - Keyword search - Autopsy Help - Autopsy and The Sleuth Kit This is running single user, Eugene Livis suggested setting up a Solr server as a cluster in a ‘Multi-user’ configuration. I will look at this option but in the meantime I though you might like to take a look a the thread-dump.
