Hi,
i'm running a node application which crashes probably once a week due to an
uncaught "Can't render headers ..." exception. The node.js version in use
is 0.8.22 and the OS distro is RHEL 6.2. i did not find the definitive
pattern of sequence of events which led to the crash though.
The stack trace looks like:
http.js:715
throw new Error('Can\'t render headers after they are sent to the
client.'
^
Error: Can't render headers after they are sent to the client.
at ServerResponse.OutgoingMessage._renderHeaders (http.js:715:11)
at ServerResponse.writeHead (http.js:1059:20)
at Socket.proxyError
(/opt/share/node_modules/http-proxy/lib/node-http-proxy/http-proxy.js:193:9)
at Socket.g (events.js:192:14)
at Socket.EventEmitter.emit (events.js:126:20)
at Socket.connect.require.lookup.addressType (net.js:699:16)
at process.startup.processNextTick.process._tickCallback
(node.js:245:9)
According to my web surfing, several developers also ran into similar
problem in the past but it is not clear to me what the culprit is. i know
the node.js version i used (0.8.22) has some age but it seems that similar
problems also exist in 0.10.10 so i'm not sure upgrading node.js helps in
this case. Moreover, to upgrade node.js in our environment is somewhat
painful and not really under my control.
Any suggestion how i can track down and rectify the problem?
Thanks.
