The "System Crashes" Panel

The "System Crashes" panel

When you click on the "System Crashes" tab, a panel appears with controls for customizing Rebound!'s system crash detection.

Monitor system for crashes

If this box is checked, Rebound! will monitor your system and attempt to restart it when a crash is detected. Uncheck this box to turn Rebound!'s system crash detection off.

Tip: It is a good idea to uncheck this box before doing any unusually processor-intensive task such as a long calculation. See "Restart if system doesn't respond" below for more information.

Restart if system doesn't respond

This slider lets you set how long the Rebound! hardware will wait before deciding that the system has crashed.

If an application runs certain long uninterruptible tasks, the normal communication between the Rebound! software and hardware can be temporarily stopped. To keep Rebound! from misinterpreting these pauses as crashes, you can set this slider to a higher waiting time.

Note: Be careful not to set this waiting time too low. The lower the waiting time, the more likely a long task will be misinterpreted as a crash.

Time allowed for system to restart

If the "Number of restart attempts" setting (see below) is higher than '1', this slider lets you set how long the Rebound! hardware will wait to reestablish communication with the software after a restart.

Normally, the Rebound! software reestablishes communication as the system finishes restarting. If the system crashes again during restart, the Rebound! software won't be able to do this. This slider lets you set how long the Rebound! hardware will wait before it decides something is wrong and tries to restart the computer again.

Number of restart attempts

This slider lets you set the number of times the Rebound! hardware will attempt to restart the computer if it crashes again during the restart process.

This feature works in conjunction with the "Time allowed for system to restart" slider above. After detecting a crash and restarting the system, the Rebound! hardware will wait for the Rebound! software to reestablish communication, signifying a successful restart. If this doesn't happen within the time allowed, the hardware can try again up to four more times.

Note: If this slider is set higher than '1' and you disable the Rebound! Extension, you may experience unwanted restarts. Be sure to set this slider to '1' before disabling the Rebound! software.
