Hi everyone,
I am using Mule as a proxy. When I do a request that generates a response
larger than ~4k characters Mule throws the following exception:
2009-jan-07 16:38:20 org.apache.cxf.phase.PhaseInterceptorChain doIntercept

Do anyone have any idea what could be wrong? I have tried the Mule mailing
list, but didnt get any response
so I am now trying the CXF mailing list.
More information could be found at

Thanks in advance,
