[phusion-passenger] file upload is timing out

[deepak]

hi,
cannot upload a 8.4 MB file.

see this error:
[ pid=10222 file=ext/apache2/Hooks.cpp:727 time=2010-05-18
07:13:14.842 ]:
Unexpected error in mod_passenger: An error occurred while receiving
HTTP upload data: Connection reset by peer (104)
Backtrace:
in 'boost::shared_ptr<Passenger::BufferedUpload>
Hooks::receiveRequestBody(request_rec*, const char*)' (Hooks.cpp:1084)
in 'int Hooks::handleRequest(request_rec*)' (Hooks.cpp:459)

TimeOut is set as 1200 in the virtalhost

transferring the file via scp took 4.1 minutes

cheers,
deepak

Someother errors are:

finish the file upload: it said it will upload 6610086\
bytes, but it closed the connection after sending 610155 bytes. The
user probably clicked Stop in the browser or his Interne\
t connection
stalled.

Another questions are:
1) is there a debug mode in passenger - verbose logging
2) can i handle the upload outside of apache and then hand it off to
passenger
3) have also tried mod_porter (http://modporter.com/) it does not seem
to help

Any help?

regards,
deepak

I don't think I can be of any help to you. This looks like some kind
of Apache issue or Internet connection issue. We use Apache's file
upload receiving mechanism so if that fails there's nothing we can do
about it. Maybe you'll have more luck at some Apache support forum.

Thanks for the reply.

can u point me to the simplest working code with upload.
Sorry if it seems noobish but i want to try another piece-of-code to check if there is a bug in my code.
The version of apache and passenger would be helpful.

Also, can the file upload be taken out of passenger. And when the file upload is complete it is handed off to passenger.

regards,
deepak

It's not your code. The error message indicates a problem in either
Apache or the network connection. You didn't do anything wrong in the
app, the problem is likely in the environment.

hi,
We are using a netscalar loadbalancer and it does seem like an
environment issue.
http://support.citrix.com/article/CTX123833 [ Unable to Upload Files
to the Backend Application Servers Using HTTP ]
http://support.citrix.com/article/CTX122322 [ Uploading Large File
though a NetScaler Appliance takes more Time as Compared to Direct
Server Access ]
http://lists.centos.org/pipermail/centos/2009-December/087887.html

sorry, if this is not the appropriate place to ask this, but has
anyone faced this problem before with netscalar loadbalancer.

Also,
1) is there a debug mode in passenger - verbose logging. I tried
PassengerLogLevel but it does not show me the files being buffered
etc. Can i log every step, would help to debug proglems (and report
bugs if any)

2) can i handle the upload outside of apache and then hand it off to

passenger. Is this question relevant?
3) is mod_porter (http://modporter.com/) supported, is it recommended?

deepak

hi,
i wanted to debug the apache process by running strace, but i do not
want passenger to spawn/kill a processes.
I want one process to be running at all times so that i can run strace
on it.

I have his configuration: http://pastie.org/979733
* why are 5 processed started even when PassengerMaxPoolSize is given
as 2
* passenger-status does not show any info under 'Domains'
* how can i tell which process is doing what, does passenger have
something like mongrel_proctitle, i can do a lsof but it is too
cumbersome.
