Daily a service restart at 07h CET (logrotate and rules), and sometimes at 16h Suricata segfaults.

From the build-info output I see that there is no debug enabled - hence most likely not so much useful information to chase the issue.
Since you mention this is reproducible - can you please recompile with - 

     CFLAGS="-O0 -ggdb"  ./configure.........

Then the coredump would be very helpful.

Thanks for the input, just reconfigured and compiled/linked again and restart suricata. See what happens coming days.

Any news for this issue? Haven't seen the same issue but very anxious for the outcome / resolution.

Well since recompiling it as requested with CFLAGS="-O0 ggdb" I've not seen any crash yet 8( Did not upgrade poring or kernel in-between so a little mytery.

Andre, do you happen to have some of the nic offloading features still on? Can you show output of 'ethtool -k <youriface>'?
