Thread dumps are creating while saving or while checking in the section. For example if I am trying to customize the "pyActionAreaButtons" section the moment I am saving the section, server hangs and it is not available for access. This is causing only when we are modifying the complex sections.
I could not able to find any information in the pegaLogs and alerts logs for investigation.
Can you please let me know, what could be the cause of the issue.
