Ok; could you please report this in a jira?
(http://issues.apache.org/jira/browse/qpid)

No, I believe the line numbers should match, so you may be looking at
source slightly different from what you're running. For now let's assume
it's just off by a line, but you should check into this further.

alwaysReadableFd is for a pipe - is there a chance you've closed it?

It's not a known problem, so please open a jira for it. Also, please be
sure you're running the same version of the code you're reading.
