unstable Travis CI builds

Hi! I've noticed that recently there is a real lot of random failures on Travis CI. E.g. this build: https://travis-ci.org/php/php-src/builds/179298649 two tests fail: ext/sysvsem/tests/nowait.phpt and sapi/cli/tests/php_cli_server_017.phpt Im different builds different random tests fail. Did we change something in Travis config or settings that may be causing this? It is really not good that our builds always fail in random places, we need to improve the stability or look for some other solution... -- Stas Malyshev smalyshev@gmail.com
