The Go SDK uses cGo in the background. In Go, when you are calling out to C/C++, the code converts the current Goroutine to an OS thread. This is a limitation of the runtime, not the Go SDK. If you are running the agent with many Go routines and make Go SDK calls within the Go routines in your application code, there may be a risk of reaching the OS thread limit. If you encounter this limitation, contact Support Information.
