Synchronization service idle check
- Martin Gudme Søndergaard
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 | 10 seconds |
If the service is in idle mode and the last database heartbeat was more than 5 minutes | 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 |
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;
