Search Head log kernels

[TISKAR]

Hello,

We have a problème with Splunk Search head, the splunk service is restarted randomly when using the launch  request or consultation of the dashbord.
After the analysis we find kernel messages at the log level.

Do you have any idea about this type of message.
