https://bugzilla.redhat.com/show_bug.cgi?id=1248968 --- Comment #3 from Petr Pisar <ppisar@xxxxxxxxxx> --- I cannot reduce it to xvfb-run only with: $ while (xvfb-run '/bin/true'; xvfb-run '/bin/true'); do :; done Perhaps because the tests kill xvfb-run before it reaches end. However putting "wait" just after kill in the xvfb-run helps. I think xvfb-run should terminate after the Xvfb terminates. Another workaround is to edit Test::NeedsDisplay to call xfbv-run with "-a". Not only it fixes the issue with overlapping Xvfb's lock file, it will also allow to use Test::NeedsDisplay in parallel. Without the option each Xvfb binds to display :99 which leads to failures. -- 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
