APAR status

• Closed as program error.

Error description

• Transactions might hang on cached document revalidation or the
  appliance might restart.
  

Local fix

Problem summary

• Affected are Datapower configurations with Document Cache Policy
  configured and caching enabled in XML Manager object.
  
  When a cached document is revalidated, and the revalidation
  fails, the appliance might restart in specific cases, generating
  a backtrace, or the transaction affected may hang, possibly
  resulting in memory leak.
  
  Currently the only manifestations known are those that match
  the following conditions: the cached documents originate from
  HTTPS URLs and are requested from a scheduled rule and the
  appliance is executing quiesce command. Other scenarios may
  exist as well, though.
  

Problem conclusion

• The fix is available in  6.0.0.18, 6.0.1.14, 7.0.0.11, 7.1.0.8
  and 7.2.0.2
