Robbie Gemmell updated QPID-3237:
---------------------------------
Component/s: Python Test Suite
> Python broker tests hang in environments where the available file handles >
> 1024
> --------------------------------------------------------------------------------
>
> Key: QPID-3237
> URL: https://issues.apache.org/jira/browse/QPID-3237
> Project: Qpid
> Issue Type: Bug
> Components: Python Test Suite
> Environment: As root, append to the /etc/security/limits.conf the
> following line to assign yourself the ability to open 64k file handles
> (substitute your login id):
> kpvdr - nofile 65536
> then log out/in as yourself.
> Reporter: Kim van der Riet
>
> When the environment is modified to allow the qpid user to open more than
> 1024 file handles, then the following python tests fail/hang. The underlying
> cause seems to be the use of the python call to select(), which uses the
> underlying unix ::select() call. However, it is a well-known limitation that
> the unix select() cannot handle more than 1024 file handles. Perhaps
> switching the tests to using epoll would solve this issue.
