3D Mesh Production - Random Tiles STUCK at 32% - 33% ! HELP

Hi guys, when processing drone dataset for 3D mesh in "High" Quality.

Random tiles gets stuck at 32% or 33%. And I have to close the CC Engine and restart. After which the tile is "Failed" and it continues with the next tile. Every 6-10 tiles, one tile gets stuck!! Some tiles were stuck for over 9 hours!

 It usually takes 30 minutes to process 1 tile successfully.

 Tile size is 120 meters, using regular planar grid.

Any suggestions??

System configuration: Intel Xeon, 128gb ram, nvidia quadro P2000
