cat <<EOT


Zend Server and Apache/Nginx are prepared to save core dumps of crashing processes.
Reproduce the crash and check that core dump files have been placed in

$ZCE_PREFIX/var/core


If you want to disable core dump creation, run this command with the '--off' parameter:

$ZCE_PREFIX/bin/support_tool.sh --core-dump --off


If you need to restart Zend Server, but keep it in core dump mode, set the proper limit before Zend Server restart:

ulimit -c unlimited
$ZCE_PREFIX/bin/zendctl.sh restart
