The idle check is a self-diagnostics function that runs every 10 seconds to check various states of the service. Its function is to trap logical locks and to ensure service-uptime. Not all of the checks are being performed every 10 seconds because some of them cost CPU-time and because the service has to be tolerant. Here is a list of checks being performed;

| Task                                                                                                                | Interval   |
|:--------------------------------------------------------------------------------------------------------------------|:-----------|
| Check for the existence of c:\cisync.debug and put the service into/out of debug mode                               | 10 seconds |
| Check for the existence of c:\cisync.dump and perform a status dump into the logfile :green_star:                   | 10 seconds |
| If the service is in idle mode and the last database heartbeat was more than 5 minutes ago then restart the service | 10 seconds |
| Check to see if any of the required firewall ports have been closed and reopen them if necessary 🔵                 | 20 seconds |
| If no jobs are either waiting or running but status \<\> idle then change the status to idle                          | 30 seconds |
| If in idle state and the last auto-update check was more than 60 seconds ago then run auto-update                   | 10 seconds |
| If in idle state and the last system update check was more than 60 seconds ago then run a system update             | 10 seconds |
| If the clock is five past then log next scheduled jobs                                                              | 10 seconds |

:green_star: Should a port in the firewall (used by ciSync) be closed for some reason while the service is running, it is logged and the port reopened.

🔵 The status dump is a block of status info written to the logfile and looks something like this;
