The error you're seeing: > [@sankard](#): > > [1]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk Is from [the system call filter bootstrap check](https://www.elastic.co/guide/en/elasticsearch/reference/5.5/system-call-filter-check.html). You can disable that at your own risk, but if possible, look into why they're failing and fix them (e.g. make sure your kernel has CONFIG\_SECCOMP and CONFIG\_SECCOMP\_FILTER compiled in). ---
