[Oisf-users] suricata freezes if no or little traffic is present on monitored interface

[Yasha Zislin]

I've tried newer version of PFRING. 6.2 and 6.3 No luck. Here is an interesting note in the 6.2 release notes:PF_RING-aware LibpcapFixed pcap_brekloop (tcpdump now handles sigterm correctly when there is no traffic)
Is this what you were talking about?
So this sensor does get some broadcast traffic. My other sensors that have similar amount of traffic on monitored interfaces dont get stuck.
On this one, I get errors when trying to stop it right after starting it. Suricata reports:<Error> - [ERRCODE: SC_ERR_FATAL(171)] - Engine unable to disable detect thread - "RxPFReth22".  Killing engine

I've enabled debugging in PF_RING and nothing shows until that message appears above.
When I try to reload rules, it starts the rebuild of grouping structure but never gives "rules reload complete" message. 
I understand your suggestion to switch to another capture method but it seems that this should work with small amount of packets on monitored interface as it does on other sensors.
BTW, I've tried Suricata-3.0 with no luck.
Thank you for your help.
