Redis server can't run more than 1024M maxheap
Redis doesn't use the conf file in its home directory by default. You have to pass the file in on the command line:
.\redis-server.exe redis.windows.confThis is what is in my conf file:
maxheap 2048Mheapdir D:\\redisheapThese settings resolved my issue.
This is how to use the maxheap flag, which is more convenient then using a config file:
redis-server --maxheap 2gb
To back up Michael's response, I've had the same problem.
I had ~40GB of free space, and paging file set to 4G-8G. Redis did not want to start until I set paging file to the amount recommended by Windows themselves, which was 12GB.
Really odd beahaviour.
