Truncated or oversized response headers received from daemon process

[Anatoly Piskunov]

Hello Graham Dumpelton, and rest of the fellow community! 

i need your competent help with this issue. I've read almost all of the threads, but unfortunately didn't get a solution.

When i run Django app from development web server,

python manage.py runserver 127.0.0.1:8000

everything works like a charm when i do curl 127.0.0.1:8000/Path_to_View/LInk?hub.verify_token=some_token&hub.challenge=some_challenge
when i don't pass get params, i see error (and that's great!!!)

But when i try access this url served by apache - i get internal server error 500.

And no error traceback shown in my virtualhost apache logs (please see below).

if i simplify views.py, as below 

class FacebookBotView(generic.View):
    def get(self, request, *args, **kwargs):
     return HttpResponse('Hello World!')

    @method_decorator(csrf_exempt)
    def dispatch(self, request, *args, **kwargs):
     return generic.View.dispatch(self, request, *args, **kwargs)

Page accessible via apache, and i get web response.

but if i make a syntax, or ident mistake, or call some function - the error comes back again, with no traceback.

And i mention again - none of this appears with dev. web server.

The process is crashing, likely because of a fault C extension module. Try adding:

    WSGIApplicationGroup %{GLOBAL}

See:

Graham Dumpleton! My best complements, regards, blessing and other stuff!!!

That worked, i'll be testing this solution for now.

and again, thanks a lot!

Hello again!

i've faced with another related problem, and rely on your competent help only!

recently, i've been posting my app. And when somebody calls my url, gets "ERR_CONTENT_DECODING_FAILED" or curl_err:23

so i added SetEnv no-gzip 1 into my VirtualHost Directory.

it now looks like:

        <Directory /home/user01/nano_fb_py_bot/nano_fb_py_bot>

        SetEnv no-gzip 1
        <Files wsgi.py>

        Require all granted
        </Files>
        </Directory>

funny thing is, when now somebody requests url, he gets

	%valid_response_string%<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
	<html><head>
	<title>500 Internal Server Error</title>
	</head><body>
	<h1>Internal Server Error</h1>
	<p>The server encountered an internal error or
	misconfiguration and was unable to complete
	your request.</p>
	<p>Please contact the server administrator at

	<hr>
	<address>Apache/2.4.7 (Ubuntu) Server at kcl16bt08.kcell.kz Port 443</address>
	</body></html>

in the apache log i see the same Truncated or oversized response headers received from daemon process

any ideas on that Graham?

[Anatoly Piskunov]

May be it's important, before i added SetEnv no-gzip 1 , i saw in apache logs that request is reaching the server, and response is sent back with no errors.

some users was even able to see correct response, but some got curl_error = Error while processing content unencoding: invalid block type or ERR_CONTENT_DECODING_FAILED.

so i dig for that problem, and found out about gzip issue.

The —compress-responses option is something to do with mod_wsgi-express, which you aren’t using.

In mod_wsgi-express what that option does is ensure the mod_deflate is loaded and adds:

AddOutputFilterByType DEFLATE text/plain

AddOutputFilterByType DEFLATE text/html

AddOutputFilterByType DEFLATE text/xml

AddOutputFilterByType DEFLATE text/css

AddOutputFilterByType DEFLATE text/javascript

AddOutputFilterByType DEFLATE application/xhtml+xml

AddOutputFilterByType DEFLATE application/javascript

You seem to want to turn off gzip, not turn it on.

Graham

[Graham Dumpleton]

Rather than set:

SetEnv no-gzip 1 

what happens when you disable mod_deflate altogether? That would turn off compression inbound and outbound for the whole server.

Understand if you can’t disable it for other reasons.

Graham

[Anatoly Piskunov]

I've just tried. Nothing changed

As in the mod_wsgi daemon process crashed and you got the truncated response error, or you are getting the error from the HTTP client?

Can you ensure that LogLevel in Apache is set to ‘info’ and not just ‘warn’.

This will cause mod_wsgi to output log messages about daemon process stopping and starting. I would like to see what these message say at the time you see the truncated response message.

Thanks.

Graham

[Anatoly Piskunov]

truncated response error - is in the apache log for my virtualhost

In the HTTP Client (e.g. Chrome) - i see html output, it's source code below ("hubChallenge" string - is a valid plain text response on requested url. somehow HTML Error 500 page is appended)

hubChallenge<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"><html><head><title>500 Internal Server Error</title></head><body><h1>Internal Server Error</h1><p>The server encountered an internal error ormisconfiguration and was unable to completeyour request.</p><p>Please contact the server administrator at webmaster@localhost to inform them of the time this error occurred, and the actions you performed just before this error.</p><p>More information about this error may be availablein the server error log.</p><hr><address>Apache/2.4.7 (Ubuntu) Server at kcl16bt08.kcell.kz Port 443</address></body></html>

Log level is set to debug for wsgi. I've performed apache start, and requested url:

There is no indication that the daemon process crashed, so it may well be the case that the response headers returned have values which are too long. This can happen when using fancy authentication challenge headers. They would need to be more than 8192 characters if using recent mod_wsgi versions.

What version of mod_wsgi are you using?

If using a recent version you could set the header-buffer-size option on WSGIDaemonProcess to increase allowed header size, but maybe first you can explain if there would be any strange headers your response returns, including authentication headers.
