Error description

• The process details REST API call takes a lot of time to run for
  process instances that contain many tasks because the data that
  is retrieved for each task is extensive.

  is often logged when the problem occurs
  [2/23/16 14:39:31:137 EST] 0000015b LoggingUtils  I   The
  elapsed time for the following REST request was 1041.36
  seconds, which exceeds the warning threshold of 60 seconds:

Local fix

Problem summary

• No additional information is available.
  

Problem conclusion

• A fix is available for IBM BPM V8.0.1.1, V8.5.0, V8.5.5, and
  V8.5.6 that introduces a new value for the parts request
  parameter on the process details API. Use
  /rest/bpm/wle/v1/process/<instanceId>?parts=excludeTaskData to
  reduce the amount of data that is returned.
