OUT OF PRIVATE HANDLES

i'm not very good on c++ and i got to develop a dll for our lotus domino server.
the problem i have is, when the dll is called about 1000 times the http-task of the domino server crashes whith following error message on the server console:
"MemAlloc: OUT OF PRIVATE HANDLES! -- pid 000004F4 Handles used so far 16953, Maximum handles = 10495"

here's the code of my dll
i think that my mistake is, that i use goto's when an error appears and i don't free the memory.
