Found this and thought it would be interesting for the group:
-----------------------------------------
This big retail chain wants to make sure it doesn't feed duplicate
orders into a mainframe system, so it tasks a Cobol programmer with
making sure that doesn't happen, reports a pilot fish in the know.
"This was 1992," fish says. "The program would check for a duplicate
order based on the order numbers stored in a table. There was a
subscript just after the table that was used to step through the
table to compare all the values.
"Unfortunately, he forgot to put a check in place to abort the
process if the table got full.
"I had always heard that the worst bugs are found within six months
after a program is put into production, and have lived with this
notion secure in my mind.
"In 2014, my buddy who still works there told me that the program
ordinarily took a few minutes to run, but one day it ran for two
hours. They canceled it and quickly found this bug.
"So much for the six month rule."
