Unexpected error in NSE_TYPE_READ callback

[micro dev <microdev1 () yahoo com>]

Hi, 
I am getting this error while I run service scan on a network. I am using NMAP 3.70 verion.
My host machine is Windows 2000 Server, SP 4
Here's what I get without -v flag 
 
C:\nmap-3.70>nmap.exe -sS --max_rtt_timeout 300 --min_parallelism 50 -T 3 -sV -p
 0-9000 -O  -oX "..\temp\NMapOutput.xml" 10.27.0.128-254 2>&1

Starting nmap 3.70 ( http://www.insecure.org/nmap ) at 2004-09-19 10:23 Pacific
Daylight Time
Unexpected error in NSE_TYPE_READ callback.  Error code: 10053 (Unknown error)
QUITTING!

C:\nmap-3.70>

 
I ran the same scan with -v flag to get more output and place where it threw this error is this -
