Hello, When I change the value for "max_file_descriptors" - say to 130000 for example - using the MAX_OPEN_FILES variable in init script, I noticed a strange behavior. The value dispalyed through API seems correct as shown below (ES version is 0.90.5) :
curl -XGET 'http://localhost:9200/_nodes/_local?process=true&pretty=true' { "ok" : true, "cluster_name" : "es-clust", "nodes" : { "5PHUSFl2TmW-3yCdisBWZg" : { "name" : "es-01", "transport_address" : "inet[/10.0.8.107:9300]", "hostname" : "es-01", "version" : "0.90.5", "http_address" : "inet[/10.0.8.107:9200]", "attributes" : { "master" : "true" }, "process" : { "refresh_interval" : 1000, "id" : 2633, *"max_file_descriptors" : 200000* } } } } At the same time, I set the *-Des.max-open-files=true* JVM option to have the value written in ES log file. This doesn't return the same value : *[2013-12-19 10:14:28,614][INFO ][bootstrap ] max_open_files [97518]* [2013-12-19 10:14:28,727][INFO ][node ] [es-01] version[0.90.5], pid[2633], build[c8714e8/2013-09-17T12:50:20Z] [2013-12-19 10:14:28,733][INFO ][node ] [es-01] initializing ...

If I set a value under this apparent "limit" - say 75000 for instance - the result seems (nearly) correct in log file (as well as through the API) : *[2013-12-19 10:28:38,002][INFO ][bootstrap ] max_open_files [74975]* [2013-12-19 10:28:38,128][INFO ][node ] [es-01] version[0.90.5], pid[2835], build[c8714e8/2013-09-17T12:50:20Z] [2013-12-19 10:28:38,128][INFO ][node ] [es-01] initializing ...

I assume - and hope ;) - that the correct value is the one displayed through the API but I'd like someone to confirm this.
