Answer 1

This is a typical stack overflow error, means a function is recursively called in an infinite loop. That is caused by a bug in that script, likely because your data is somehow corrupted and the script is not able to stand that.

Try to call the script with the --verbose flag, or check the log files for error messages. Try to find the error in your data by running the script testwise with reduced data input (e.g. without tickets).
