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 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

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.

2011-10-28 08:07:01:526 - Firewall info  : On profile: Domain, port 8037 is open and now enabled

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