This is caused by insufficient virtual memory. Insufficient memory in the virtual machine is caused by too many programs running and the virtual memory setting is too small.

Then select “Custom size” and open the settings After that, the virtual memory window will pop up, as shown in the figure. ​

When setting the virtual memory size, the bigger is not the better. It should be set according to our actual physical memory, which is usually 1.5 of the actual physical memory. -About 2 times. For example, my computer memory is 4G. It is recommended to set the virtual memory size between 4096M and 8192M. After the input is completed, click the "Set" button, as shown in the figure. Note: 1G=1024M
