However, you'll certainly run out of memory at some point, and searching linked lists degrades in performance as they get larger, so there's certainly limits somewhere. I highly doubt anyone has come close to 50k exports before. You're backtrace is parsing the config file, so maybe large config file parsing becomes slow?
