The amNaming log sometimes indicates multiple Site Monitor threads running for checking the same site. To prevent this problem, OpenSSO Enterprise 8.0 Update 1 provides improved synchronization to prevent the creation of the multiple Site Monitor threads for the same site. OpenSSO Enterprise 8.0 also includes these new 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.
After you set these properties, restart the OpenSSO Enterprise 8.0 web container for the new values to take effect.
The fix for this problem also uses the following property:
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).
