I though it was caused by upgrading xorg-server, but it fails even with old xorg-server 1.17.2-2. It's a race condition between stopping and starting Xvfb. In case of the failure, one can see that Xvfb from t/10_run.t is still running, so second Xvfb refuses to start and X client cannot open display (both Xvfb are terminated or xauth does not match) and xvfb-run killing the second Xvfb fails because it finishes before the killing. -- You are receiving this mail because: You are on the CC list for the bug. -- Fedora Extras Perl SIG http://www.fedoraproject.org/wiki/Extras/SIGs/Perl perl-devel mailing list perl-devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/perl-devel
