Trying to run the onsmsync command to expire some old backup information, but everytime I run it I keep getting an Out of memory error. I've tried upping the ulimit memory values, as well as trying older dates, but no joy. Any suggestions?

ukbiprodmvrs01[/home/informix]$ onsmsync -t "2010-05-01 00:00:00"
malloc() failure

ukbiprodmvrs01[/home/informix]$ tail -f /informix/informix11.50FC3/log/nwc_bar_act.log
