First of all, I'd like to thank everybody who has tried to help. In fact this is why we write here and UNIX wouldn't be UNIX without the long-standing tradition of one helping the other and constant discussion of every aspect of our work. I'm thankful for every of you being here.
Still, it is also a long-standing tradition that "help" in our part of the society means "help to help yourself". This means: the one seeking help should show some genuine effort first to solve his problem. The thread-opener did no such thing. And there is also a long-standing tradition inherited from countless newsgroups in the comp.* hierarchy to ignore people who don't uphold this tenet.
I'd like to ask you therefore to NOT answer such threads - not until O/P has shown this genuine effort by presenting whatever he has undertaken to accomplish his task. This was exactly the point of my answer. Please hold back on such threads until O/P has answered - and if he doesn't bother to do so, then so be it.
We are all professionals here and - like me - you probably met one or the other "colleague" in your career who tried to let others do his work. You perhaps do not want to support or encourage persons once they cannot get favours from their immediate co-workers any more, do you?
So, please, use your judgement and refrain from answering threads as long as O/P has not shown some willingness to work himself before.
Thank you for your consideration.

async_daemon
async_daemon(2) System Calls Manual async_daemon(2)
NAME
async_daemon - Creates a local NFS asynchronous I/O server
SYNOPSIS
async_daemon(
unsigned long iod_num,
unsigned long magic);
PARAMETERS
Specifies the number of I/O threads to run. For Tru64 UNIX, this is 950410. If a different value is used, seven NFS I/O threads are run.
DESCRIPTION
The use of the async_daemon() function is not supported in customer applications, and the interface is subject to change without notice.
It is intended for use solely by nfsiod(8).
The async_daemon() function starts iod_num NFS I/O kernel threads that are used to improve NFS I/O performance. This function does not
return to the caller, but remains in the kernel to provide additional support for NFS over TCP.
RETURN VALUES
The async_daemon function has no successful return. In fact, it frees the text and data segments associated with the calling program so
there is nothing to return to. When interrupted by a KILL signal, the I/O threads are terminated and the process exits. If the async_dae-
mon function encounters errors, , -1 is returned and errno is set to indicate the error.
ERRORS
If the async_daemon() function fails, errno may be set to the following value: The async_daemon function has already been called by another
process. The caller is not the superuser. More than 64 I/O threads were requested. The kernel memory allocator has no memory.
