Hi gratchie,  I'll be glad to help.  Your timing is impeccable, as EMC has just released a MR update of InsightIQ.  See if you can download this new build:  InsightIQ 4.0.1 is available as of Wednesday, 5/18, as a General Availability release. The release is available on Support Zone effective immediately.  In the meantime, I think a while ago I ran into a similar issue as you did. It turned out that I didn't run the self-installation .sh file with sudo.  Could you verify?  Thanks.
I downloaded and installed "install-insightiq-4.0.0.0049.sh" but insightIQ is unable to run properly. I populated /etc/isilon/insightiq.ini with the needed info and made sure that cache_dir exists and is writable.
