redis thinks you don’t have enough memory, so it won’t open a second instance for you. The Windows version of Redis allocates a large memory mapped file for sharing
the heap with the forked process used in persistence operations. This sentence makes it very clear
Solution:
1: Change the maxheap parameter in redis.windows.conf
maxheap 10240000
I failed to solve the problem using this method
2: Start adding the maxheap parameter
redis-server.exe --maxheap 10240000
How many 0s are configured according to the data situation, not too many

This file will be created in the current working directory or the directory specified by the 'heapdir' directive in the .conf file. Windows is reporting that there is insufficient disk space available for this file (Windows error 0x70). You may fix this problem by either reducing the size of the Redis heap with the --maxheap flag, or by moving the heap file to a local drive with sufficient space. Please see the documentation included with the binary distributions for more details on the --maxheap and --heapdir flags. Redis can not continue. Exiting.
