PHP Script running on the command line died during echo()

[pieseesax]

I have a script that runs on the command line, called by a crontab. In the last five attempts to run this script, it has died partway through an echo statement - the cron output only shows part of the intended echo output, and nothing after that is executed. This is a long-running script, being run through php-cli, which performs file management tasks.Is there anything that might cause a script to die during an echo statement, without generating any other output, or a way to troubleshoot or catch potential errors during echo?I am not sure what code I can post that will help, as this is a rather comprehensive script involving a few libraries. The echo statements are fairly simple - echo('Checking file...') might get put in the log as "Che" then no more output.
