  • Cisco Adaptive Security Appliance (ASA) Software

Known Affected Releases

8.4(6.5)

Description (partial)

Symptom:
Under rare conditions, an ASA may get stuck in a reboot loop when upgrading the software version. A traceback in the pix_flash_config_thread will be generated.

Conditions:
This issue happens when the ASA is being migrated from a pre-8.4 software version to any 8.4 version of software. The startup-config must contain a name, an ACE that references that name, and 2 object-groups with similar names. For example:

  names
  name 10.1.0.0 MY_NAME description MY_NAME
  object-group network MY_NAME_1
   description Created during name migration
  object-group network MY_NAME
   description Created during name migration
  access-list 100 extended permit ip MY_NAME 255.255.0.0 any inactive
