  • Closed as program error.

Error description

  • An application that uses SERVER_ENCRYPT authentication to connec
    t to a DB2 database may hang or trap.   When SERVER_ENCRYPT auth
    entication is used DB2 will use an ICC library to encrypt the us
    erid and password that is sent to the database server.  If the a
    pplication process that is connecting uses too much stack space
    then the ICC library may get a stack overflow which could result
     in a hang or a trap.
    

Local fix

  • If possible increase the stack space of the application process
    or do not use SERVER_ENCRYPT authentication.
