I recently upgraded to 4.3.4 and I'm getting the following error on my searches:
|inputcsv networks.csv | fields ip
Error in 'inputcsv' command: You have insufficient privileges input a file from var/run/splunk. You can input a temporary csv file (emitted by outputcsv within the same search) by passing 'dispatch=t' as an option.
Permissions on the .csv file are good and I'm running this search as admin.
