Error description

  • If you have IBM Process Portal open in multiple tabs in the same
browser (same user in each tab), in one tab CometD tries to
reconnect every two seconds. If it reconnects successfully,
CometD changes to the regular 30-second polling for this tab
and, for the other tabs, CometD starts trying to reconnect every
 two seconds.

Problem summary


    

  • Because the multiSessionInterval property is not defined and
configured to 30 seconds, it defaults to 2 seconds when Process
Portal is open in multiple tabs in the same browser window,
resulting in very frequent attempts at long polling.

    



Problem conclusion


    

  • A fix for IBM BPM V8.5.0.0, V8.5.0.1 and V8.5.5.0 is available
that introduces the multiSessionInterval property
and sets it to 30 seconds.
