Service Queue functions incorrectly

SA-106343

Summary



All processes are executed asynchronously in the Pega application. The maximum number of execution attempts is configured as 3, in the Service Request Processor data instance. However, despite configuring the out-of-the-box ProcessServiceQueue agent to execute for 5 minutes, all the three attempts occur within a minute and run on only one node.

Steps to Reproduce

  1. Queue the Service Request to process case updates (such as, notes or documents). The case update must be an opened case (having a lock or is locked by the user).
  2. Retain the lock on the case in the Case Manager portal. 

Root Cause



A defect in Pegasystems’ code or rules.
