Arducam 64mp random *** failed to allocate capture buffers *** with added cma-512

Hi! Pi 4 with 2G here. I’m getting random errors with memory allocation. Sometimes command needs to be executed several times to capture an image. dtoverlay=vc4-kms-v3d,cma-512 was added. CmaTotal: 524288 kB CmaFree: 426756 kB Shooting in JPG usually works fine. Adding -r for Raw output crashes randomly. Will post logs in next post repeating command after it fails without changing anything eventually works. I guess this is software problem. Lets fix it.
