The CDP operations become unstable and the following error message appears:
The error occurs due to an insufficient memory amount caused by an issue in Task History Clean-up. When the clean-up process starts, it consumes all available memory and brings the whole system to a halt.
In CDP 3.14 this problem will be fixed. But for now go to Configuration Server Options and click "Edit Schedule" in the "Task History Clean-up" tab.
Then set the trigger type to "Never."
This will prevent Task History Clean-up from running and taking up the memory.
This step should only be taken after ensuring that the heap space is properly configured and that it is not a low-memory situation. See Configuring Heap Memory.
