Message216392
Trying to build Python 3.4.0 for Fedora we are seeing test_asyncio test_subprocess_send_signal hang every time, on all architectures. Unfortunately I cannot reproduce this locally. These builds are done inside of chroots, and the host has the kernel version 3.12.8-300.fc20 which is used for all build targets. We see hangs building for Fedora Rawhide and RHEL 7. We do *not* see hangs on our COPR builders which among other possible differences use RHEL6 hosts with kernel 2.6.32-358.el6.
I've attached an strace of the hanging test. The calling process seems to be stuck in epoll_wait().
Tried using the watchdog patch from issue #19652 but that doesn't seem to manage to kill things. In fact, the tests are never killed but the 1 hour timeout in the test runner. |
