The CDP operations become unstable and the following error message appears:

java.lang.OutOfMemoryError: Java heap space


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.
