Stuck Outbound Queues in CRM system

Question

Hi Guys,
In CRM system the out bound queuse for the Sales Orders got stuck with the following error "Too many recursive subroutine calls"
The Sales Orders are not getting replicated from the CRM system to R/3.
The business partners associated with the sales orders are getting replicated to the From CRM to the R/3 system.
anyone has clue regarding the issue.

Answer 1

upon debuggin we found the follwoing nformation
In debugging the program it states the following:
Too many recursive subroutine calls.                                                                               
What happened?                                                                               
Error in ABAP application program.                                                                               
The current ABAP program "SAPLCC01" had to be terminated because one of the   
statements could not be executed.                                                                               
This is probably due to an error in the ABAP program.                                                                               
What can you do?                                                                               
Print out the error message (using the "Print" function)                      
and make a note of the actions and input that caused the                      
error.                                                                               
To resolve the problem, contact your SAP system administrator.                
You can use transaction ST22 (ABAP Dump Analysis) to view and administer      
termination messages, especially those beyond their normal deletion          
date.                                                                               
Error analysis                                                                               
An ABAP/4 subroutine was called recursively too often.                        
This is probably due to a conversion exit or a user exit                      
triggering the same exit again and again.                                     
These exits are implemented by function modules with the names                
CONVERSION_EXIT_xxxxx_INPUT/OUTPUT or USER_EXIT_xxxxx_INPUT.                  
You can find out which ABAP/4 subroutine is affected in the               
section "Active Calls / Events".                                          
Conversion exits are triggered during screen field transports or          
WRITE statements, field exits during field transports from the            
screen to the ABAP/4 program, so they are not called directly by          
an ABAP/4 program. Most likely, this is due to the implementation         
of a conversion exit which contains a WRITE statement for a field         
to which the same conversion exit is assigned in its Dictionary           
domain. As A result, the exit is triggered                                
recursively.                                                              
You can make up to 50 ABAP/4 subroutine calls.                            
How to correct the error                                                                               
Probably the only way to eliminate the error is to correct the program.   
You may able to find an interim solution to the problem                   
in the SAP note system. If you have access to the note system yourself,   
use the following search criteria:                                                                               
"RPERF_TOO_MANY_CALLS" C                                                  
"SAPLCC01" or "LCC01U05"                                                  
"PCA_CHECK_LUHN_MOD_TEN"                                                  
If you cannot solve the problem yourself, please send the                 
following documents to SAP:
