IC76589: CLEARING THE STYLESHEET CACHE MAY CAUSE A RESTART ON A SYSTEM RUNNING DATA TRAFFIC

APAR status

• Closed as fixed if next.

Error description

• When the stylesheet cache is cleared via WebGUI or CLI command,
  e.g. "refresh stylesheet default *" and the appliance is serving
  requests via WSGW using these stylesheets, the firmware may
  restart. A workaround is to bring the relevant WS-Proxies down
  before clearing the stylesheet cache.
  

Local fix

• Quiese the WS-Proxy before clearing the cache.
  

Problem summary

• Customers using Web Service Proxy service may be affected.
  
  When a stylesheet being used by a WS Proxy service is cleared
  from the cache using WebGUI or CLI, and data traffic is being
  processed by the service at the same time, the firmware may
  reload.
  
  This is due to a programming error in handling the stylesheet
  cache.
  

Problem conclusion

Temporary fix

• Quiesce a WS Proxy service before clearing a stylesheet
  referenced by it from the cache. This is a recommended best
  practice anyway.
