I followed the official documentation to install the golang environment, cloned the repository to my wsl environment, and ran go run main.go The following exception occurred

Can someone help me solve this problem?

[bhima2001]

i am also facing the same issue.

[Misaki030112]

#908

I found this issue and its associated PR that solved the problem I was having for the first time.

in fact，

If the KeysLimit value is not configured in this code, the default value is 200 million, which results in the channel requiring at least 9.6GB of memory.

Key(16bytes)+Operation(16bytes)+Value(16bytes)=48bytes

48bytes×200,000,000=9,600,000,000bytes=9.6GB

My memory is 8GB, and the available memory is less than 8G all year round, which will cause OOM.
