Hey Guys, Suricata generated this output today that has crashed the 'Suricata -> Blocks' option.
Looks like an obfuscation attempt. Could be consequences of an attack, see attached file.
I've tried stopping and restarting the interfaces but the issue has not resolved itself. May have to do a complete reinstall.

Crash report begins.  Anonymous machine information:
