"There are not enough free threads in ThreadPool to complete the operation."

When booting using multiple threads, I received the following error message:

ThreadPool did not have enough free threads to complete the operation.

Should I try to change the default settings for threadpool in .net and how to do it?

AspNetServer:

if (Thread.GetDomain().GetData(".appDomain") == null)
{
    Thread.GetDomain().SetData(".appDomain", new object());
}

. System.Net.NclUtilities.IsThreadPoolLow:

if (ComNetOS.IsAspNetServer)
{
    return false;
}

System.Net.ComNetOS .ctor():

IsAspNetServer = Thread.GetDomain().GetData(".appDomain") != null;
