My "Err_Flag" is my file descriptor. 

 ***********************************************************            
C     Sb_SetFile    BegSr                                               
                                                                        
C                   Eval      Oflag = O_CREAT + O_CODEPAGE +            
C                                     O_RDWR                            
                                                                        
C                   Eval      Omode = S_IRWXU + S_IROTH                 
                                                                        
C                   Eval      Filename = %Trim(Filename) + Null         
                                                                        
C                   Eval      Err_Flag = Open(%Addr(Filename) : OFLAG : 
C                                        Omode: CodePage)               
                                                                        
C                   If        Err_Flag < 0                              
C                   ExSr      *Pssr                                     
C                   EndIf                                               
                                                                        
C                   Eval      Rc = Close(Err_Flag)         
                                                           
C                   EndSr   

At the end of the process the same RC = Close(Err_Flag ) is used this is the 
code:
0628.00  ***********************************************************
0629.00  * Sb_ClsFile - Close PC File in IFS directory              
0630.00  ***********************************************************
0631.00 C     Sb_ClsFile    BegSr                                   
0632.00                                                             
0633.00 C                   Eval      Rc = Close(Err_Flag)          
0634.00                                                             
0635.00 C                   If        Err_Flag < 0                  
0636.00 C                   ExSr      *Pssr                         
0637.00 C                   EndIf                                   
0638.00                                                             
0639.00 C                   EndSr                                   
0640.00                                                             

If had any error closing I believe a dump will have been produced.

I think the problem is more likely that you're not closing a file or 
directory properly. I simply can't imagine that you legitimately have 
hundreds of file descriptors open.

The parameter to the close() API is the descriptor that you want to close. 
It's not an error flag.

Does your program check to see if Rc is -1?  If it is, it means that the 
close is failing and therefore something is wrong with your code.
