Suricata rules failed

[kunalhiremath]

Currently I am running securityonion 2.3.130 in that suricata version is 6.0.5. One week before everything was working fine but two days back I saw my alerts page in securityonion dashboard was not showing any alerts.

After checking suricata logs I found some errors.

Errors:
