Issue
The services fail to start after editing table-map.xml or index-concentrator-custom.xml files during custom meta key management. During a service restart you may notice the following errors in /var/log/messages file:

Module logdecoder failed to load: Diagnostic information: Throw in function nw::XmlNode& nw::XmlDocument::pop()
Dynamic exception type: nw::XmlError
std::exception::what: ERROR: pop() - XmlDocument stack is empty.
[boost::errinfo_at_line_*] = 1499
[boost::errinfo_file_name_*] = /etc/netwitness/ng/envision/etc/table-map-custom.xml
Cause
The xml file is corrupted or incorrectly modified.
Resolution
You can identify the error and validate an xml file using "xmllint" program. xmllint  is a command line XML tool that can perform XML validation.

Example:
Login to an ssh session on the Log Decoder and then execute the following command:
xmllint validate /etc/netwitness/ng/envision/etc/table-map.xml

Login to an ssh session on the Concentrator and then execute the following command:
xmllint validate /etc/netwitness/ng/index-concentrator-custom.xml
