Hey @Siddhant , can you check if your disk is out of space or not? SIGBUS usually happens when you are out of disk space.
If you see badger/memtable.go at d918b9904b2ac71316a75e04fc54427a3bbd06bf · dgraph-io/badger · GitHub, we are copying the data to mmaped file. So, disk space seems to be the cause of SIGBUS.
