Briefly, this error occurs when Elasticsearch is unable to link to the C library’s native methods, resulting in the disabling of seccomp (secure computing mode). This could be due to an issue with the system’s library path or a missing library. To resolve this, you can ensure that the required libraries are installed and the library path is correctly set. Alternatively, you can disable the bootstrap.seccomp filter in the Elasticsearch settings if it’s not needed, but this could potentially expose your system to security risks.
