Error description

• DB2 server may trap in ICU (International Components for
  Unicode) library code. Function sqlnlsICUopen_UCA400 will be
  displayed in the stack as the top DB2 function.
  
  This problem has been observed only under high user load and is
  very rarely seen. It also happens only on Windows OS and does
  not occur with DB2 V9.5.
  
  You also need to have your database created using UCA400_NO
  collating sequence.
  
  Below is a condensed stack trace you may see after you formated
  the trap file:
  
  ...
  <_sqlnlsICUopen_UCA400.> <sqlnlsCollationOper.C:219>
