When starting multiple nodes at once (with a script of some kind), failure to load unmanaged dll can occur:

{code}
for (int i = 0; i < 30; i++)
{
	Process.Start(@"cmd.exe", @"/k Apache.Ignite.exe");
}
{code}

Exception:
{code}
ERROR: System.TypeInitializationException: The type initializer for 'Apache.Ignite.Core.Impl.Unmanaged.UnmanagedUtils' threw an exception. ---> Apache.Ignite.Core.Common.IgniteException: Failed to load ignite.jni.dll: 126
