TroubleshootingAlertHost database disabledLogging configuration errorUnable to open Content GatewayManagerICMP echo failed for a default gatewayHTTP origin server is congestedCongestion alleviated on the HTTP originserverDescriptionThe host database stores the DomainName Server (DNS) entries of originservers to which the proxy connects. Ittracks:• DNS information (for fast conversionof host names to IP addresses)• The HTTP version of each host (soadvanced protocol features can be usedwith hosts running modern servers)• Host reliability and availabilityinformation (to avoid waits for nonfunctionalservers)Content Gateway can be configured to logtransactions, errors, or both to a locationthat you specify.See “Working with Log Files” in theContent Gateway Manager <strong>Help</strong> forinformation about logging.Content Gateway is unable to set up asocket to handle management API calls tostart the <strong>Web</strong> interface.A Content Gateway node failed to contactits default gateway while assigning virtualIP addresses for a cluster. The node willshut down.When Content Gateway is deployed as a<strong>Web</strong> proxy cache, user requests for <strong>Web</strong>content pass through Content Gateway onthe way to the destination <strong>Web</strong> server(origin server).When a client requests an HTTP objectthat is stale in the cache, Content Gatewayrevalidates the object, querying the originserver to check if the object is unchanged.If the origin server is congested (unable toaccept additional connections), and doesnot respond to the revalidation query, theproxy does not perform any validation; itserves the stale object from the cache.An origin server that previously deniedconnection attempts is now acceptingrequests again.<strong>TRITON</strong> - <strong>Web</strong> <strong>Security</strong> <strong>Help</strong> 511
