Hi.
I'm using CXF 3.0.4 in client proxy mode, using my server REST interfaces.
In addition I'm using the httpclient cxf module to workaround earlier problems
with concurrency
under load (as suggested by Sergey in a post some months ago here on the
mailing list).
For Multipart handling I'm using the jersey MultiPart JAX-RS MessageBodyWriter
on the server
as well as on the client.
Under normal circumstances all goes well. But sometimes, especially on the
startup-phase of the load test,
the CXF client proxy dies with the exception below during a Multipart POST. Any
clue what might cause this?
