JR54776: WITH COMETD NOTIFICATIONS ENABLED, A BROWSER MEMORY LEAK MIGHT OCCUR IN IBM PROCESS PORTAL

Version 8.5 Refresh Pack 7 for the IBM Business Process Manager products

APAR status

• Closed as program error.

Error description

• If CometD push notifications are enabled on the IBM Business
  Process Manager (BPM) server, you might experience net growth in
  the amount of memory that the browser uses while IBM Process
  Portal runs. During a Process Portal session, this growth might
  accumulate to the point where the browser and the workstation on
  which the browser runs become unresponsive.
  
  PRODUCTS AFFECTED
  IBM BPM Advanced
  IBM BPM Standard
  IBM BPM Express
  

Local fix

Problem summary

• Client-side code that runs in the browser does not properly
  release memory objects associated with CometD channel
  subscriptions (each channel subscription is for a specific set
  of notifications from the IBM BPM server) when those
  subscriptions are terminated, resulting in a browser memory
  leak.
  

Problem conclusion

• A fix is included in IBM BPM V8.5.6.0 cumulative fix 2 (CF02)
  that properly releases memory objects associated with CometD
  channel subscriptions as the subscriptions are terminated.
