System maintenance
The system should be the only application installed and running on your machine. Other applications running on the same machine as the system cause unnecessary performance problems. For example, disk space shortage, memory shortage, or the reduction of swap space:
- Swap space:
The engine shuts itself down if virtual memory on the machine is 90% exhausted. At 95% exhausted, the MonitorD does not start.
- Full file system:
All message saving is disabled when the /integrator file system is greater than 90% full. At 97% full, all engine output is disabled, and the engine shuts down. The MonitorD and engine do not start when the file system is 95% full or greater.
Part of maintenance is booting the system machine on a consistent basis. The system machine should be booted at least every two weeks. Rebooting helps prevent problems before they happen, and reduces calls to Support. Restarting your machine stops and removes zombie processes and resets virtual memory.
