Hello,
We are using Tomcat 7.0.61 and we are seeing the following error in
catalina.out:

We are also seeing this, which also happens with stream.close() around the
same time:

The ³org.gravity² package is GraniteDS, a third party library we are
using. I can tell you what is happening:
1. GraniteDS is calling flush() on an output stream. This is throwing a
ClientAbortException. I think this is the first error seen above. You can
see it in the call stack (AbstractChannel.runReceived).
2. In the catch block, GraniteDS is calling close() on this stream. This
causes the 2nd and 3rd error seen above.
We are having some stability issues with Tomcat, Tomcat crashes right
after one of these happens. It doesn¹t crash every time. Is this a bug in
Tomcat or APR? Is there anything we can do to avoid it?
Thanks
