Ebadf (bad File Descriptor) Android
lots of times like 50 reload/10 seconds it gives me this error: events.js:45 throw arguments[1]; // Unhandled 'error' event ^ Error: EBADF, Bad file descriptor This seems to me like a bandwidth error or something like that, originally I've got the error when I played with the HTML 5 Audio API, and If I loaded the audio file 10-15 times sequentially then I've got the error, but now I've discovered that I get the error ebadf bad file descriptor python without the Audio API too just by reloading the site a lots of times, also Safari gives me the error much faster than Chrome (WTF?) I'm using Node.js 0.4.8 with express + jade and I'm also connected to a MySQL database with the db-mysql module. I can't find any articles on the web about this topic what helps, so pleeease let me know what can cause this error because it's really confusing :( node.js file-descriptor share|improve this question edited Jul 14 '11 at 5:49 asked Jul 14 '11 at 4:39 Adam 13.1k42100169 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote accepted By "reload your application" do you mean refresh your app's home page from a browser, or actually stop and restart the node.js server process? I assume the former, in which case if you can't reliably reproduce this it will be pretty tricky to debug, especially since you don't have a good stack trace to pinpoint the source. But if you use the express.js app.error hook (docs here) you'll want to log the error path from the "Bad file descriptor" error, which should hopefully clue you in to whether this is a temporary file that got deleted or what. In terms of the actual cause, we can only offer guesses since "Bad file descriptor" is a very generic low

Milestone No milestone Assignees No one assigned 3 participants edsu commented Jun 16, 2011 Just wondering if anyone has seen this error pop up intermittently when node is under load: events.js:45 throw arguments[1]; // Unhandled 'error' event ^ Error: EBADF, Bad file descriptor I haven't been able to reproduce it with a test. But have tried both trunk and v0.4 http://stackoverflow.com/questions/6688552/node-js-ebadf-bad-file-descriptor (stable). My app does use socket.io. Is this perhaps some limitation of my system? Can anyone recommend some ways I could help figure out what is going on here? edsu commented Jun 16, 2011 @acdha helped me tune my TCP stack to more aggressively reap connections, since I was getting close to a thousand on my small linode VPS ... so my problem was lower level than node. If you are curious I lowered both of these https://github.com/nodejs/node-v0.x-archive/issues/1189 from 60 to 30: sysctl net.ipv4.tcp_fin_timeout=30 sysctl net.ipv4.tcp_tw_recycle=30 tommedema commented Jun 16, 2011 What does this do? It would be really helpful if someone could create a guide with all these settings, including http agent settings etc. so that the rest of us do not need to experience such downtime ourselves when services get popular. edsu commented Jun 16, 2011 Basically I did a netstat --tcp and noticed a lot of connections in TIME_WAIT. The number of connections grew and grew to about 1000 connections, and then I think I hit some practical system limit (eventhough ulimit said there was no limit, there is a practical limit). If anyone knows how to determine the limit it would be interesting to know how to do that. The sysctl commands basically lower the time that a connection will be kept alive, which causes connections in TIME_WAIT to be reaped sooner. I'm not sure that it completely fixed my problems, but at least node isn't getting a fatal exception for now. edsu commented Jun 17, 2011 I think this is some system tuning issue and not anything to do w/ node, so I'm closing this ticket. edsu closed this Jun 17, 2011 slajax referenced this issue in expressjs/express Oct 31, 2012 Closed Error: EBADF, close #1393 slajax commented Nov 1, 2012 I'm seeing this consistently with express 3 in bot

With connect 1.4.3, I am occasionally getting events.js:45 throw arguments[1]; // Unhandled 'error' event ^ Error: EBADF, Bad file descriptor It was bad file much worse on Tuesday AM, prior to running npm update connect to get to version 1.4.3 (I saw some mentions of static in the git logs). Since then it ran about 48 hrs serving hundreds of large-ish files (between 2 and 8 MB) to about 10 processes, but then it died again. I just upgraded to 1.4.4, and will see if it continues. Is there any way to bad file descriptor turn on more verbose messages to track this down? Sencha Labs member tj commented Jun 17, 2011 hmm i think i know what this is, because on a failure we close the read stream, however if it's already you will get EBADF tj added a commit that closed this issue Jun 17, 2011 tj #297 … should do the trick 5e21d09 tj closed this in 5e21d09 Jun 17, 2011 jmarca commented Jun 17, 2011 Super awesome. I'll run that version now. jmarca commented Jun 17, 2011 Still seeing the crash with the latest version. It has crashed twice so far today. I will try to set up a callback function to dump more information on the crash. Sencha Labs member tj commented Jun 17, 2011 shit, is it a really shallow stack trace? or can you post the rest? Sencha Labs member tj commented Jun 17, 2011 weird i reproduced it kinda tj reopened this Jun 17, 2011 jmarca commented Jun 17, 2011 Sorry I posted every

When starting it with node server.js it works like a charm but when starting it with nohup or forever node.js can't find the files. javabeangrinder Answer Email {} Share It turned out to be the file path of the file that was the problem. When running the server using node the working directory is the same as the server.js file thus node.js manages to find the file. When starting whilst using nohup or just starting with forever the working directory doesn't seem to be the same as server.js. I solved this by prepending the global variable __dirname to the filename.
