I don't see a commit for this in maintenance-3.4, it would be good to get this in (and into trunk) - and as the sanity build on this branch will have the release artefacts available we could get someone to verify the fix.

Subject: Re: [fcrepo-user] Occasional random (FilterSetup) Can't do next doFilter() error It is the same bug. This is the process that cause the bug 1 .Fedora opens a stream to the data, and stores the stream in an object. 2. Said object closes the stream when it is finalized Often fedora then discards the object storing the stream, and passing the stream on. But if the garbage collecter finalizes the store-object before the stream is read, the stream is closed. So far, we have regarded the bug to be not serious enough to warrant a new release. I think it is fixed in the 3.4 Maintenance branch. The only known workaround is to ensure that the fedora server is never put under load, and have way to much memory, as this will hopefully prevent the garbage collecter from running very often.
