2477404 - Server fails to start and reports 'engine has died' message with stack containing keipanic - SAP ASE


  • ASE engine crash when starting > 1 engine
  • Either startup with multiple engines or use sp_engine to add additional engines
  • ASE log contains message 'engine has died' with a stacktrace including 'keipanic' function :

Engine 0 (os pid 1234) has died, server is performing emergency shutdown
end of stack trace, kernel service process: kpid 456789
ueshutdown: exiting

  • ASE does not crash immediately at startup (or with sp_engine) but crashes as soon as the first user activity / query is run
  • Behaviour is slighly different depending on the LD_POINTER_GUARD variable. It crashes in both cases, with :
    • LD_POINTER_GUARD=0 it kills engine 0
    • LD_POINTER_GUARD=1 kills other engines randomly
  • OS settings in /etc/sysctl.conf :
    • kernel.exec-shield=0
    • kernel.randomize_va_space=0
    • vm.legacy_va_layout=1



  • SAP Adaptive Server Enterprise (ASE) 15.0.x & 15.5
  • Recent Linux distributions, but exact versions are not known with certainty:
    • Linux Redhat 7.x
    • SuSE 11 SP3 or higher
