Hi Jörg,

No solution yet. I still get it occasionally on two different machines. I'm pleased (sort-of) that someone else is also encountering this. What is your platform and which version of FC are you running?

Hello Janna,

i've got the same problem. The Servlet Interface is running fine, but with the Rest API appears the error. Do you already found any solution? 

Thanks you in advance for your help.

I occasionally (and randomly) receive the following error when retrieving large (100-2000) numbers of managed datastreams in succession:

ERROR 2010-10-21 09:00:59.934 [TP-Processor11] (FilterSetup) Can't do next doFilter()

(The full error log is attached.)

I've seen this error in FedoraCommons versions from 3.0 up to the latest 3.4.1. The error this morning occurred in a 3.4.1 repository using the Akubra storage module, the FC supplied Tomcat running under (RHEL's) Java 1.6.0_22 on an up to date RHEL 5.5 system.

It can happen if I'm retrieving a succession of (managed) descMedatata datastreams (MODS) using the REST API; it can also happen if I'm retrieving a succession of (managed) PDF2TEXT datastreams when I'm updating a Solr index - again via the REST API. I've been totally unable to force the error to occur. In most cases, I'm the only user accessing the FC repository.

It's more of a nuisance than a show-stopper; I just have to remember to check my application's error log each time.

Is this a Fedora problem or a REST API problem or a Java problem or a RHEL+Java problem or ???

Thanks muchly!
