I don’t know if this applies to Solaris as well, but the default ephemeral port range on AIX is 32768 to 65535. Any port number in this range is subject to use by OS processes (i.e., CL engine, monitord, etc.).
If this is the case, the only 2 options that I know of are:
1. Change the ephemeral range. (not really advised)
2. Change the client to a different port number outside the range.
This should only apply to inbound connections to your system.
Hope this helps.

I had this problem last week on my Dev system.
