If you don’t change any configuration one day and somehow open the redis server to flash back, you can enter the redis-server directory in the command line and enter redis-server.exe redis.windows.conf command to view the error information
If an error is reported as follows
QForkMasterInit: system error caught. error code=0x000005af, message=VirtualAllocEx failed
It means that you have not set the maximum memory of redis
Open redis.windows.conf with Notepad
Add the code below to the last line.
maxmemory 268435456
maxheap 314572800
