These errors will show up if a page load time is longer than the CGI Script Timeout setting in IIS. At times, this may be normal if the user is requesting a large search. However, if these messages are frequent, it may indicate a performance problem in Service Desk. If this is the case, you may want to open an issue with Support to identify the cause.
