IT24944: DATABASE MARKED BAD (SQLO_INV_PARM) ON INTERRUPT IN REGULAR EXPRESSION PROCESSING

APAR status

• Closed as program error.

Error description

• This is the same issue as PI73641 which is a BigSQL APAR:
  http://www-01.ibm.com/support/docview.wss?uid=swg1PI73641
  
  This is being opened so we can fix the same issue in DB2 v11.1.
  
  During an interrupt, the database can panic and shut down when
  DB2 is handling a regular expression (REGEX).     In the
  db2diag.log you would see an error like this:
