When reviewing your servers in your environment settings page, you may see that your server is not being monitored due to this error:
Monitoring failed to start: Cache file size exceeded per the header. The file's total size '420180202' (limit is '419430400') or the file's update size '0' (limit is '157286400') exceeded the allowed limits.
This can happen if your dataset size is larger than expected, due to a large number of urls being monitored, a large number of websites on your server, or other factors.
If so, you can increase the local cache size by following these steps:
1. Edit your c:\leanserver\sentinelrecorder\preferences.config file
<add key="AddServers" value="." />
2. Restart the LeanSentry Monitoring service
