logical logs

Hi I am running Online 7.23 on HP 10.20 Why was logical log backed up every 2-3 minutes? Is there any hint not to make that backup too fast? Here is the info... 11:07:08 Logical Log 608 Complete. 11:07:09 Process exited with return code 133: /bin/sh /bin/sh -c /usr/informix/etc/log_full.sh 2 23 "Logical Log 608 Complete."
