Tom Carter, a computer consultant with Clover Link Systems of Los Angeles, said the application has a hard limit of 32,000 changes in a single month.
“This probably seemed like plenty to the designers, but when the storms hit last week, they caused many, many crew reassignments, and the value of 32,000 was exceeded,” he said.
