I believe the issue to lie in the buffer tag. I'm suspicious of the org.apache.myfaces.custom.buffer.HtmlBufferResponseWriterWrapper and its toString() method which closes the writer.
Using the buffer tag on a page exposes this issue under a moderate load (approx 20 users with an 'intense' business action or query). Using the same logic on a page without the buffer tag is fine. --- Michael Hartman <[EMAIL PROTECTED]> wrote: > I've been getting 'Stream closed' exceptions with a MyFaces-based web app. > See stacktrace > below. > Happens under low/moderate load (less than 10 users).
