Error Ebadf Write
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 without the Audio API too just by reloading the site a lots of times, also Safari gives me the error nodejs ebadf 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 level error that basically means you are calling an operation on a file descriptor that is no longer in the correct state to handle that operation (like reading a closed file, opening a file that has been deleted, etc). share

But have tried both trunk and v0.4 (stable). My bad file 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 from 60 bad file descriptor 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 both my dev and prod en
