--- Comment #13 from Rainer Jung <rainer.j...@kippdata.de> ---
I can reproduce errors even for trunk but there currently only read timeouts.
I'm using a relatively slow server and remote access from a more powerful
machine using 10 threads in the improved version of the WebCrawler. Crawling
the docs/ webapp suffices to produce those read timeouts (30 seconds). The CPU
on the server is not fully saturated and other parametrization shows that those
requests would hang indefinitely if no timeout were applied.

For TC 7.0.50 I could also produce other types of errors, but didn't play long
enough with trunk.

Not directly related to the read timeout occurences I see on the server side
sometimes messages:
