during photos pairswise matching

  my computer is  64am   3070x2  i9-10900k  ,  and   now  i have a question  for   CC   modeling,    This project has 24000 photos, which have passed the aerial triangulation calculation. In the model production process, it is divided into 66 blocks, and the estimated memory of each block is 40Gb, but six of them failed,andthe error message is during photos pairswise matching.

  In the forum, I saw that some experts said they wanted to delete some cache files, but I didn't know it was those files.Has anyone met a problem similar to mine and how to solve it??
