The cause is that GLIBC_2.14 is missing:
{code}java.lang.UnsatisfiedLinkError: /tmp/jboss-eap/modules/system/layers/base/org/apache/activemq/artemis/journal/main/lib/linux-x86_64/libartemis-native-64.so: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /tmp/jboss-eap/modules/system/layers/base/org/apache/activemq/artemis/journal/main/lib/linux-x86_64/libartemis-native-64.so){code}

However GLIBC is present on RHEL 6 but in older version 2.12. I've read something around this and problem is that libartemis-native-64.so was compiled on RHEL 7 where is newer GLIBC_2.14 version. So libartemis-native-64.so should be compiled on RHEL6 to fix this.

Just from curiosity when I tried to compile glibc-2.14 and added it to LD_LIBRARY_PATH AIO got loaded on RHEL 6.
