Hi David
Thanks very much for your insights.
After poking around a lot I seem to have tracked down the issue that
is giving the headaches:
Whenever a client is stopping the initial download of a file, the
created cache results in a corrupt file.
ie: if I download a (so far uncached) large pdf of 4mb and click on
cancel in the download manager at 2mb the cached file has only a size
of 2mb and naturally all subsequential downloads will receive a
incomplete/corrupted file.
this on its own is already annoying - now toss in IE7 and downloads
with a meta refresh to make 90% of your downloads corrupt. tasty!
So the only way to guarantee that this won't happen anymore is to
totally disable cache on the dms (or wherever your downloads are
stored) - which also rather s*cks.
Has someone an idea how to avoid this issue and still be able to work
with caching?
Does this qualify as a bug and should I file a jira-entry?
brgds, Thomas

Thanks for the stack trace. The error occurs on the connection
between tomcat and the client. Neither Jackrabbit or the BDB are
at fault here. Something between your tomcat server and your
client browser is disrupting the connection. I would investigate
firewalls, network switches, and ethernet cables as possible
culprits. Does this happen with one particular client machine or
does everyone get this problem? That'll tell you which end to look
at.

If you can make anything of it I am more than happy to hear about it.

Hi Thomas. Could you post the whole stack trace to your
ClientAbortException including root cause? This may not have
anything to do with the persistence layer, but with firewalls or
bad network equipment interrupting the transfer.

Hello Claudio
Thanks for the input.
Unfortunately I'm not clear where I would configure the
connection string or timeout setting.
Any further explanation is highly appreciated.
File sizes range between 200k to 10MB.

Hi Thomas
I use Magnolia in combination with MYSQL, not Derby or BDB.
However I
had a similar exception in my logs once, caused by database
disconnects.
I managed to get rid of them by specifying
"Autoreconnect=true" in the
connection string. However I don't know if you could do the
same on
Derby or BDB.
Is there some sort of timeout setting for the Derby or BDB?
Does it only
happen with bigger files?

Subject: [magnolia-user] ClientAbortException:
java.net.SocketException:
Broken pipe
Hi List
I have a rather puzzling issue that arises in multiple projects:
whenever I try to pull downloads from the dms I get a
ClientAbortException: java.net.SocketException: Broken pipe
and as a result a corrupted file in the download. It happens with
different files (zip/pdf/mov) in different projects.
Magnolia Version: 3.0.2 with BDB and 3.0.5 with derby on different
OS's (linux/OSX)
Can someone give me a clue how to avoid this?
TIA for any pointer!
Thomas
