Hi, I have a script in node-js that do a lot of http requests.
After 30s, I did 30 000 requests, and I start having errors : `connect EHOSTUNREACH` and `getaddrinfo ENOENT` The command `netstat -putone` tell me that there are a lot of sockets in TIME_WAIT state: ... tcp 0 0 10.26.164.13:50180 10.26.165.15:9023 TIME_WAIT 0 0 - timewait (0.00/0/0) tcp 0 0 10.26.164.13:57571 10.26.165.14:9023 TIME_WAIT 0 0 - timewait (0.00/0/0) tcp 0 0 10.26.164.13:59341 10.26.165.14:9023 TIME_WAIT 0 0 - timewait (0.14/0/0) tcp 0 0 10.26.164.13:50219 10.26.165.15:9023 TIME_WAIT 0 0 - timewait (0.00/0/0) tcp 0 0 10.26.164.13:41825 10.26.165.16:9023 TIME_WAIT 0 0 - timewait (0.00/0/0) tcp 0 0 10.26.164.13:57264 10.26.165.14:9023 TIME_WAIT 0 0 - timewait (0.00/0/0) tcp 0 0 10.26.164.13:41151 10.26.165.16:9023 TIME_WAIT 0 0 - timewait (0.00/0/0) ... $ netstat -putone |grep TIME_WAIT |wc -l 31413 Is there a way to tell the OS to reuse the sockets in TIME_WAIT state ? I read docs about SO_REUSE_ADDR : http://www.unixguide.net/network/socketfaq/4.5.shtml, and it's looks what I need. Now I am wondering how to pass this option to the tcp socket. But a grep told me that SO_REUSE_ADDR is used in lib_uv. https://github.com/joyent/node/blob/master/deps/uv/src/unix/stream.c#L90 I don't understand how lib_uv works. Is anybody could help me ? Cheers Romain PS: for information the script is this one: require('async').forEachLimit(_.range(100000), 5, function(data, next){ var request = require('request'); var hosts = ['tpsmdu11s', 'tpsmdu12s', 'tpsmdu13s']; var host = _(hosts).shuffle()[0]; var reqOpts = { url: 'http://' + host + ':9023/_search', method: 'post', timeout: options.timeout || 10000, body: '{ "a json document": { ... } }' }; request(reqOpts, next); }); -- Job Board: http://jobs.nodejs.org/ Posting guidelines: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines You received this message because you are subscribed to the Google Groups "nodejs" group.
