the assertion detects that a page has a too high number (page numbers are stored in 5 bytes in log records and checkpoint record, so they should not be >= 1<<40); here the page number is 2251799813685247 which 2048 * 1<<40 - 1. The assertion is good, there must be a bug elsewhere in Maria. We should check where hash_link->pageno is set.
