**Elasticsearch version** (`bin/elasticsearch --version`): 6.4.0
**JVM version** (`java -version`): adoptOpenJDK 10
**OS version** (`uname -a` if on a Unix-like system): Linux abc8c2c59c04 4.4.132-94.33-default #1 SMP Tue May 29 20:09:56 UTC 2018 (76aae3b) s390x s390x s390x GNU/Linux
**Description of the problem including expected versus actual behavior** :
Built ES6.4.0 from the source, build and TC execution are successful but I am getting below warning message after starting Elastic search service on s390x,
> [2018-08-22T12:21:45,517][WARN][o.e.b.JNANatives] unable to install syscall filter:
> java.lang.UnsupportedOperationException: seccomp unavailable: 's390x' architecture unsupported
Even though the service is started, we want to resolve the warning by adding below line to `elasticsearch/server/src/main/java/org/elasticsearch/bootstrap/SystemCallFilter.java`
> m.put("s390x", new Arch(0x80000016, 0xFFFFFFFF, 1, 190, 11, 354, 348));
According to my observation, after adding the patch the test suit execution speed reduced drastically and many test cases failed.
1. Anyone experiencing the same behavior on non-intel architectures ?
2. what would be the effect of that warning message "seccomp unavailable: 's390x' architecture " on ES service if we don't resolve ?
