Cover Count Error, Negative values for cover count
SA-81026
Summary
Error occurs on submitting a case. This occurs intermittently.
Error Messages
The cover open count is incorrect; it is -1
Steps to Reproduce
Close the sub cases. The validation is in the Activity- Resolve of the Pega-ProcessEngine:08-01-01 ruleset.
Root Cause
Any value higher than 1 caused the system to read the page from the database before checking if the object is lockable. This introduced a timing window, in which another requestor may have updated the page beyond what is read from the database. Hence, a stale page is delivered.
Resolution
Perform the following local-change:
Include the below setting in prconfig.xml:
<env name="database/maxlockattempts" value="1"/>
