CreateObject ("MSXML2.serverXMLHTTP.6.0") and CreateObject ("WinHttp.WinHttpRequest.5.1") crashes while running 100 objects / requests

I am trying to create 100-300 HTTP objects / requests at the same time using MSXML2.serverXMLHTTP.6.0or WinHttp.WinHttpRequest.5.1.

These queries are created in separate threads using a test application. Everything works fine, up to 90 creating objects / queries launched simultaneously.

When more than 100 are created / called at the same time, the application crashes with an exception in KERNELBASE.dll.

the code:

CreateObject("MSXML2.serverXMLHTTP.6.0")
CreateObject("WinHttp.WinHttpRequest.5.1")

set obj = CreateObject("MSXML2.serverXMLHTTP.6.0")
'set obj = CreateObject("WinHttp.WinHttpRequest.5.1")

obj.open "GET", "https://httpbin.org/get", true
'https://resttesttest.com/

obj.send   ' Mostly crashes here.
obj.WaitForResponse

result =  obj.responseTEXT

set obj = Nothing

Event Viewer Report:

Invalid module name: KERNELBASE.dll, version: 6.1.7601.18015, timestamp: 0x50b83c8a Exception code: 0xc00000fd Error in the module path: C: \ Windows \ syswow64 \ KERNELBASE.dll
