> Components: C# - Library
> Affects Versions: 0.8

>
>
> On a linux system with single cpu core, TThreadPoolServer(csharp) might throw
> an exception like "Error: could not SetMinThreads in ThreadPool".
> According to SetMinThreads description in MSDN:
> If you specify a negative number or a number larger than the maximum number
> of active thread pool threads (obtained using GetMaxThreads), SetMinThreads
> returns false and does not change either of the minimum values.
> The default DEFAULT_MIN_THREADS value is 10, while GetMaxThreads obtains 100
> and 4 on a single-cpu computer. This make SetMinThreads function failed.
> The number obtained by GetMaxThreads is associated with the number of cpu
> core.
> So I suggest to change the order of SetMinThreads and SetMaxThreads, like:
> {code}
> if (!ThreadPool.SetMaxThreads(maxThreadPoolThreads,
> maxThreadPoolThreads))
> throw new Exception("Error: could not SetMaxThreads in
> ThreadPool");
> if (!ThreadPool.SetMinThreads(minThreadPoolThreads,
> minThreadPoolThreads))
> throw new Exception("Error: could not SetMinThreads in
> ThreadPool");
> {code}
