Hi, Due to an incompatible fix in recent kernels (to resolve CVE-2017-1000364), the Java module in syslog-ng crashes. This is used for example by the Elasticsearch destination. Right now the workaround is to use a kernel without the fix. Follow https://github.com/balabit/syslog-ng/issues/1562 to see any updates on the issue.
