[development] Cron run exceeded the time limit and was aborted.

I have a function that runs a few updates and displays a list of what it did. In order to get caught up from a long period of neglect, I decided to add it into the hook_cron. Every time I invoke cron, I get "Cron run exceeded the time limit and was aborted" yet it completes in far less than 30 seconds. Any ideas how my code could be inadvertantly triggering this?   Nancy Injustice anywhere is a threat to justice everywhere. -- Dr. Martin L. King, Jr.
