11.8 Possible explanations for a frozen image

The image may die or hang up without issuing any useful message, either at run time or possibly during delivery. Some possible remedies follow:

• Deliver the application at a lower delivery level.

  If things work after this, try the same level, but override the changed keywords one by one.

• Retain more packages, with the keyword :packages-to-keep.

  For example:

  (deliver 'application-entry 
              "application" 
              5 
              :packages-to-keep '("LISPWORKS"))
  

  The COMMON-LISP package normally should not be deleted or smashed, so it is unlikely to cause problems , but LISPWORKS and the packages defined in the application itself are worth investigating.

  If this gets the image working again, try to discover why the package is required and see if you can eliminate this requirement. See 10.8 Symbol, SYMBOL-NAME and package issues during delivery for more information on keeping and throwing away packages.
