Solution to redis error Windows error 0x70

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

D:\soft\redis-2.8.19>redis-server.exe

The Windows version of Redis allocates a large memory mapped file for sharing
the heap with the forked process used in persistence operations. 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.
