PI34909: DEPLOYING APPLICATION THAT INCLUDES A WINDOWS 8 PUSH SENDER MAY RESULT IN HIGH SERVER CPU UTILIZATION

IBM MobileFirst Platform Foundation Interim Fix README for 6.3

APAR status

• Closed as program error.

Error description

• Deploying a MobileFirst Platform Foundation application that
  includes a Windows 8 push sender to a MobileFirst Platform
  Foundation Server (using the development server embedded within
  MobileFirst Platform Foundation Studio, or using a standalone
  server) may result in unusually high CPU utilization at idle.
  The server may be observed to be fully utilizing an entire CPU
  or CPU core.  This high CPU utilization grows each time the
  application is deployed, even though the application is not
  performing any activities - each subsquent deployment may
  result in the server fully utilizing an additional CPU or CPU
  core, until all available CPUs or cores are exhausted.
  

Local fix

• The MobileFirst Platform Foundation Server may be stopped and
  then restarted to temporarily relieve the unusually high CPU
  utilization.
