[PM2][ERROR] Error while launching application Error: Process could not be forked properly, check your system health

GIVE ME SOLUTIONS OR ANY OTHER ALTERNATIVES FOR PM2 HELP ME

I’m using Digitalocean Ubuntu 20.04 Droplet.

dotnet core sdk version 2.1

pm2 version 4.5.6

I’m giving these commands:

dotnet restore

dotnet build

dotnet publish

cd ../publish folder

pm2 start xxxxxxx.dll --watch --name webapi

It’s showing this error:

[PM2] Starting /root/xxxxxxxx_API/xxxxxxxxx.API/bin/Debug/netcoreapp2.1/publish/xxxxxxxx.API.dll in fork_mode (1 instance)

And also tried these commands also pm2 start -i 3 "xxxxxx.dll" --watch --name webapi.
