Unable to download the attachments

[zzkozak]

Hello,

I've a debian squezze rootserver with OpenXchange installed (current Version : 6.20.0 Rev8 (2011-04-21 12:43:06)). It's the latest available via aptitude.

It is working perfect since 2 years. Since a few weeks I encounter the problem, that I'm unable to download the mail attachments. The download is starting, but nothing happens for minutes. Then the download is stoping and only a chunk of the file has been downloaded (if I download a JPEG, only a quarter (1/4) of the picture will download).

Next, I wanted to show the source file of the EMail (right mouse button on EMail -> Show Sourcefile), a clean OX Window appeared ... and after a while the following dialog from browser (snipped):

oxProblem.JPG

Another thing which I noticed is, the "refresh" button is spinning all the time and not only if I clicked it.

Does anyone know what the problem could be?

Thanks in advance!
zzkozak

Hi,

please check the OX log file for any error messages when downloading the image. Could also be browser/proxy/apache related.

Hi,

no Exception in "open-xchange.log.0" after starting to download the attachment (it's not only a JPEG problem, PDF and other too), but I found this exception:

Other logfiles (apache) don't report any problems/errors. It's strange, because with other mail client like iPhone there are no problems to view the attachments.

It's ture, I'm behind a proxy now, but when I try it at home without a proxy, I encounter the same behaviour ... attachments can't be loaded and the reload button on the top of the screen (to the left of the help button '?') is permanently rotating.

Hi,

okay - then please use firebug, get to the console tab of it and check for requests that are queued up or not finishing. Using OX with a proxy won't work in many cases due to ip and cookie checks. Is the OX server itself behind a proxy, even if you access it from home?

Greetings

Hi,

so I started firebug and checked for such requests, and the only one that was not ok was this:
firebug_error.JPG

Also a PUT ajax call was not ok, but answered with code 200:

Additionally I switchted the loglevel to FINEST and got this error messsage, which points to the AJP13 connector:

The OX server isn't behind a proxy.

Hi,

also downloading from Infostore is affected with the same problem.

Mostly small files < 20k can be downloaded, but not always. If the email contains more than one attachment, and one of them is small, I can't download it too.

Cheers,
Marcin

Hi,

please check the "Answer" tab for that "200 OK" Request. Judging from the first image it seems like not all requests are answered correctly. Is there any module installed that limits request/response size at apache? Actually it seems very environment related.

Hello Martin,

"Antwort" is empty. When not downloading an attachment, under "Netzwerk" I see the following:

The whole URL shows:

Hello Martin,

I got it .... it was ... like in many cases ... Kaspersky. I switched it off and everything working fine. It seems like they did an update last time, which resulted in such behaviour.

Update:
Seams like it isn't Kaspersky but the proxy settings of them. They was set to be automatically recognized, this didn't worked. It worked after setting them directly.

Thank you for your help,
Cheers,
zzkozak
