Can't upload a presentation #939

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi there,

I have issues uploading a presentation. I have tried to upload different 
formats (office 2003 .doc and .pdf). Both of those files are less than 1 mb.

Each time I try to upload a file, it stucks at the following message:

"Upload completed. Please wait while we convert the document" (see attached 
screenshot)

The loading bar stucks at 0%. After 30 minutes, I logout...

now here my bbb-conf -c output:

As you can see, it's pretty clean...

Below here an output from my /var/log/bigbluebutton/bbb-web.log after I try to 
upload a presentation

I can't see any issue on the log. It seems it generates properly the PDF. Any 
idea why it doesn't input anything on the client side?

Please help!

Best regards

Following your FAQ about slices never finish converting, I tried to restart 
Tomcat6 and Red5 services, but I still have the same issue

I read that the issue might be caused by a lack of RAM. So I asked my hosting 
provider to raise my RAM above 2 gigs. Here my new bbb-conf -c output

Is your hosting provider providing you 2G of dedicated RAM or "burst ram".  
We've seen examples where the "burst ram" doesn't work and the slide conversion 
just dies on one of the processes.

Try to add a crossdomain.xml file for the flash client in the root of your 
domain with this content:

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM 
"http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
  <allow-access-from domain="*" />
</cross-domain-policy>

File must be world-visible, no start/end leading spaces, and try again.

I had a similar issue and my system consumed more than 2,4 GB of RAM while 
converting.

We're trying to narrow down this problem.  So far ... from the logs, it seems 
the process hangs in line 92 of

https://github.com/bigbluebutton/bigbluebutton/blob/master/bigbluebutton-web/gra
ils-app/services/org/bigbluebutton/web/services/PresentationService.groovy#L92

which is

def processUploadedPresentation = {uploadedPres ->
// Run conversion on another thread.
new Timer().runAfter(1000)
   {
      documentConversionService.processDocument(uploadedPres)
   }
}

never gets executed.  It's not clear why this works consistently on some 
servers and not others.

Is this still occurring in 0.8-beta?

I have the same problem. I watch log at var/log/bigbluebutton and see that i 
miss som folders at var/lib/tomcat6/work such as 
Catalina/localhost/bigbluebutton . I create thiese folders and gave chown 
tomcat6:admin and chmod-R 777
This help to resolve problem.

Problem was update messages were being lost when sending to red5.

We put in some fixes to upload presentation problems related to the conversion 
process hanging.

Hi

My big blue button install is disconnecting my host user after they upload a 
document...just at the converting stage.

Looking at the last post on this...can you share what the fixes were please? It 
would be greatly appreciated.

Thanks
Stuart
