The amNaming log sometimes indicates multiple SiteMonitor threads running for checking the same site.
To prevent this problem, patch 8 provides improved synchronization to prevent the creation of the multiple SiteMonitor threads for the same site. Patch 8 also includes these new configuration properties:
com.sun.identity.urlchecker.retry.interval specifies the time interval in milliseconds between retries for a URL connection. Default is 500 milliseconds (0.5 seconds).
com.sun.identity.urlchecker.retry.limit specifies the maximum number of retries for the URL connection if a connection failure occurs. Default is 3 retries.
The fix for this problem also uses the following property, which was added for patch 5:
com.sun.identity.urlchecker.sleep.interval specifies the time interval in milliseconds that the site status check should sleep. Default is 30000 milliseconds (30 seconds).
The patch does not add these new properties to the AMConfig.properties file. To use these properties with values other than the default values:
For each property that you want to set, add the property and its value to the AMConfig.properties file.
Restart the Access Manager web container for the values to take effect.
