12031 Error Apache Server..........

Hi Guys,

Iam getting 12031 error when      if(!HttpEndRequest(hRequest, NULL,
0, 0)) is executed I have tested every line debugging i find No Errors
but when the debugger reaches this line in the Below given code  the
Error is generated. i have seen that this error is generated due to
SERVER_CONNECTION_TERMINATION is any chenge required in the code or
any Server Configuration has to be done. Using Apache
Server.............
