----------------------------------
Hi Robin,
I've modified your patch slightly to also close the output stream and catch any
IOException that is thrown - not sure what good it will do to let this
propagate up to Cocoon.
I've tested the code on the latest build of the trunk (checked out today) and
it fixes the leak.
Cheers

> BitstreamReader file descriptor leak
> ------------------------------------
>
> Key: DS-755
> URL: https://jira.duraspace.org/browse/DS-755
> Project: DSpace
> Issue Type: Bug
> Components: XMLUI
> Affects Versions: 1.5.2, 1.6.2
> Reporter: Gareth Waller
> Assignee: Robin Taylor
> Priority: Major
> Attachments: BitstreamReader-1.patch, BitstreamReader.java
>
>
> The BitstreamReader class opens a file descriptor to a bitstream via a call
> to "retrieve()" (line 325) but this file descriptor is never closed thereby
> causing a leak.
> This can be replicated by clicking on the View/Download links in the item
> landing pages and constantly checking the open file descriptors on the
> server. The result of this means that the max process limit for open file
> descriptors can be met if the service is under heavy load.
> This has been observed in v1.5.2 and the code looks to be the same in v1.6.2.
