2621704

Description: Fixed the resource number size (a 64 bit number) to avoid a scenario where it overwrote it with a 32 bit number and erased the high bits when de-allocating the resource number.

In this scenario, when two resource numbers had identical low 32 bits, and because the high bits were cleared, it resulted in the same idx. Consequently, when two idxes were identical, then it freed the same idx twice.

Keywords: Resource number size, free_4k page

Discovered in Version: 26.30.1004

Fixed in Release: 26.31.1014
