Copy your verthash.dat from your node to your pool server and add this to your pool config entry:

"vertHashDataFile": "path/to/verthash.dat",

i fresh setup and all done but when run pool i still see this error

VTC data file consumes > 2GB of RAM.

Thanks for your reply.
My RAM size is 16GB and I am currently using 10GB.

[konstiantyn]

32GB of RAM, 8 vCPU cores, but the same.

When MC just dies without any meaningful output its almost always a native system call that fails such as memory allocation of file opening. Try inspecting the generated core dump for Miningcore.exe or dotnet.exe on your system using gdb.

Thanks. fixed by rebuilding MC
