Edith Birrer commented on AXIS-2574:
------------------------------------

I also have this problem (using Axis 1.3, I cannot upgrade to Axis 1.4 because 
of problem AXIS-2585). 
It blocks an important project of ours. Any idea if and when this problem will 
be fixed?

>             Project: Apache Axis
>          Issue Type: Bug
>          Components: Basic Architecture
>    Affects Versions: 1.2.1
>            Reporter: Steve Sowerby

> When reading the data from an attachment we periodically get the following 
> error:
> java.io.IOException: Resource has been deleted.
>  at 
> org.apache.axis.attachments.ManagedMemoryDataSource$Instream.read(ManagedMemoryDataSource.java:688)
> Having run this throught a debugger and had a brief look at the code it seems 
> to me there is a race condition of sorts.
> The MemoryManagedDataSource that provides the InputStream has been marked as 
> deleted by the finalize method of AttachmentPart.
> So basically if the client doesn't read off the attachment fast enough then 
> the writer will have finished and the AttachmentPart gets finalized and blam, 
> you've got a deleted MemoryManagedDataSource.
> I'm not sure what the best fix is.  Perhaps the deletion should actually be 
> some reference count rather than a simple boolean.  That way the 
> MemoryManagedDataSource gets deleted once all the writers and readers are 
> done?  Although perhaps then there would be an issue if the client was very 
> slow to even open the attachment?
