After running latest update Suricata (in-line) mode is not starting and showing this error

Hi,

In my case Suricata stopped abruptly after starting with the same error. So I found out the reason why it happened so. The problem was with Netmap. Snort and Suricata in in-line mode both had issues with Netmap.

Hi,

You need to check this >> Suricata / Alerts - can't clear alerts:
https://redmine.pfsense.org/issues/5932
I had an issue with the alert.log file. It was deleted and replaced after 1 or 2 days, though it was set to autorotate at 7 days with a 10 MB limit.
