PHPUnit started randomly failing within Hudson shell

Question

Nothing within the environment has changed, nor has the test suite itself. The XML report generates correctly, but not the HTML. Please help!

Generating code coverage report, this may take a moment./tmp/hudson3472766550808527893.sh: line 3: 5237 Terminated
/usr/local/bin/phpunit --verbose -d memory_limit=1024M --log-junit ../../build/logs/phpunit.xml --coverage-clover ../../build/logs/coverage/clover.xml --coverage-html ../../build/logs/coverage-html/

Any help would be greatly appreciated. This is negatively affecting our dev. team. Below is the latest error message.

Answer 1

Something terminates the PHP process before it completes, but it is not possible to tell the reason from this log. Check the syslog on the server, it may have some hints about what is going on.

Answer 2

We had Problems with PHPUnit running out of Memory, when the Memory available on the Server was low ... just to give you a hint ... (we used apache to start the tests, and there would be arount 10 processes, each eating 2GB of memory ...) the tests started to fail randomly.

Another issue is that you might have with, is high Memory Usage ... this might be caused by phpunits restore global state functionality. If you disable it, you have to cleanup after your tests so they wont disturb the other ones, but you will use less memory.

Answer 3

As the number of files being included for code coverage grew, the memory usage grew. This question is similar to, but not the same as, the link below.
