Suricata totally stops intermittently. Cannot determine why it crashes. The files I have attached are not necessarily from the moment in time when a crash has occurred.

If you could share the following would be very helpful in the investigation:
- stats.log after the crash
- Suricata starting command line
- yaml configuration (mask out the home/ext nets if needed)
- suricata.log
- any observations as to when it happens (certain time during the day/week, etc.)

Ideally if possible a full trace would be nice - compiling with debug flags enabled -

Suricata starting command line: suricata -D -c /etc/suricata/suricata.yaml -i eno4

The crash times appears to be random. I am running a cron job that restarts Suricata every 30 minutes until we can figure out why it is crashing. That cron job also clears the eve.json file.

The interface is connected to a span port on core switch. Plans are place the interface on a gigabit tap; possibly optical.

Noticed that stats.log is not currently enabled. Will enable it.

Suricata crashed so I am submitting stats.log file and a suricata.log file.

Is it possible that crashes are occurring because Suricata 5.0.0 is running on Unbuntu 16.04.6? I just upgraded kernel to 4.4.0-170-generic and rebooted the system.

Out of curiosity - have you observed any crashes since those upgrades?
