500 Threads spawned on PegaRULES Elastic search



Environment performance declines. As a result of subsequent analysis of the problem, a marked increase in Java threads is observed within the JVM.

Error Messages

The following error message is observed in the systemout logfile:

Steps to Reproduce

There is no specific use case to replicate this behavior.

Root Cause

The source of these threads has been traced back to the Pega Process Commander ElasticSearch functionality.


To resolve this issue, without employing ElasticSearch functonality, the functionality is disabled using the following procedure:

Update the Process Commander Dynamic System Settings (DSS)

Add the following switches to DSS:

indexing/distributed/search_enabled - false
indexing/distributed/index_enabled – false
indexing/distributed/enabled – false

NOTE: In the Search landing page, uncheck the checkbox titled “ENABLE INDEXING”.
