APAR status

• Closed as program error.

Error description

• Attempting to use excessive concat() arguments (over 800
  parameters) might cause an unexpected restart of the DataPower
  appliance.
  

Local fix

• Split up the concat into multiple variables, e.g. have half of
  the concat arguments assigned to variable1 and the rest assigned
  to variable2  Then concatenate variable1 and variable2. Keep
  each variable to 200 or fewer arguments.
  

Problem summary

• Affected is the use of XPATH concat() function with a huge
  number of arguments.
  
  Compiling a stylesheet with a really huge number of arguments
  (seen with more than 800, but might happen with more than 200)
  might restart the DataPower appliance.
  

Problem conclusion

• Fix is available in 5.0.0.11 and 6.0.0.3.
