Insight - flowd broken - no log rotation

[raneyda]

I reset the Insight and netflow in the last week because there wasn't any data showing.  It started showing up after that but has again stopped.  I noticed that the /var/log/flowd.log is showing 222M even though it was rotating correctly yesterday but hasn't yet today.

Did the flowd log rotation break?  What is causing this unpredictable Insight behavior?
