I have setup a list of corn, Some of the corn script takes long time like 1-5 hours, and its increasing day by day. I do not want to run two corn script at the same time, its not for the dependency, bu its because my server memory is not that much so that it can not handle two big operation, so i need to find out a solution so that the scheduled scripts will not start until the other previous script no finished. i have 10-15 corn job in the list. and 5 of them i do not want to overlap. Anyone help me find out any solutions?
