This is a kernel parameter and requires a reboot. It is bad habit to enforce kernel parameter change from an application. This is due to the administrator.
Note that increasing vm.max_map_count is only required for applications that use many small mmap calls (with mlockall, Elasticsearch does not). A number which is too high will potentially increase memory consumption on the server and reduce performance. Jörg On Tue, Oct 28, 2014 at 3:53 PM, Suny <[email protected]> wrote: > Hi.
