Oninit from cron leaves engine in permanent fast recovery

Hi We have a requirement to automatically bounce our 9.40.FC6 instance on AIX 5.2. The idea is to use cron (informix) to run a script that sets the correct environment, etc. and then issues a 'onmode -yuk', sleeps for 30 seconds then issues a 'oninit -v'. This script ... and a cut-down wee version ... runs simply and beautifully from the informix shell. But, when cron executes the script the instance stops cleanly but fails to restart. We have compared environments and have not found anything obvious that could account for this strange behaviour. Have any of you experienced anything like this before? I have included the output from the script for both shell and cron methods of execution. I have not included any configuration information as yet. This would appear to be a deep-rooted problem, possibly to do with process management under AIX ... or something like that ... ?! My AIX/UNIX knowledge doesn't stretch that far! Thanks in advance for any help anyone can offer.
