The Administrator of a Secure Global Desktop (SGD) deployment running SGD 5.4 and the January 2019 maintenance patches receives reports that users are unable to authenticate with the SGD environment during peak usage time, with the following error message:
After receiving this report, the SGD Administrator found records of this response written to the Webservices logs (catalina.out) at the time of the outage:
Apr 05, 2019 10:01:11 AM org.apache.catalina.core.StandardWrapperValve invoke
INFO: org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1; The markup in the document preceding the root element must be well-formed.
parse: org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1; The markup in the document preceding the root element must be well-formed.
Under pressure, the SGD Administrator restarted SGD services on this node. This action resolved the report temporarily, but the behavior returned as the server returned to peak usage the following week.
