I found my cluster health is red,
and the es receive log events less and less The phenomenon as follow: So I checked the log of elasticsearch. (more details：https://github.com/crazw/biglog/blob/master/elasticseatch.log ) information: http://blog.thetaphi.de/2012/07/use-lucenes-mmapdirectory-on-64bit.html]]; nested: IOException[Map failed: MMapIndexInput(path="/home/elasticsearch/data/elasticsearch/nodes/0/indices/logstash-2014.10.01/3/index/_hi_es090_0.tim") [this may be caused by lack of enough unfragmented virtual address space or too restrictive virtual memory limits enforced by the operating system, preventing us to map a chunk of 3054244 bytes. Please review 'ulimit -v', 'ulimit -m' (both should return 'unlimited'), and 'sysctl vm.max_map_count'. More information: http://blog.thetaphi.de/2012/07/use-lucenes-mmapdirectory-on-64bit.html]]; ]] So what should I set the value of vm.max_map_count . Does anybody have such experience and give me a suggestion? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
