Catch an error in ILE PRG

Hi,

I did 2 programms,Program A, that is checking a IFS folder every 10 seconds and 
if there is any files inside, then calls to Program B. This Program B with the 
IBM XML Toolkit (QXML4PR400) reads the files and writes the data in our DB. So 
far so good. We have this system in about 10 different customers and we process 
more than 1000 files per day (all together). In just one of our customer we 
have a problem, and in 6 months (time that the process is already tunning), the 
Program B crashes. The Log is the following:

Pointer not set for location referenced.
Function check. MCH3601 unmonitored by QXML4PR400 at statement 0000000001, 
instruction X'0000'.
The call to ABC_UPDATE ended in error (C G D F)

The Program A calls the Program B like this:

     C                   call      'ZO1084'
     C                   parm                    strFile
     C                   parm                    strFromII

Is there a easy way of if this error comes again, just to stop the Program B 
without making Program A also crash. (Doesn´t really matter what is happening 
with the XML file and the data)?
Some sort of Try / Catch (like Java) in RPG?

Thanks a lot 

Mit freundlichen Grüssen
