官方解释

https://github.com/ethereum/go-ethereum/issues/14633

You will not be able to mine on a 32bit OS (or running a 32bit version of Geth). The ethash mining DAG requires more memory than the 32bit address space allows. Please use a 64bit machine, 64bit OS and 64bit verision of Geth if you wish to mine.

解决办法

解决办法1（推荐）：换成64位的geth就可以了
解决办法2：降低geth的缓存大小

查看geth是32位还是64位

shell> geth version

执行结果：

Geth
