Resolution:

1.       Please verify whether your file system having disk space issues ($df -h in case of Linux). One of the causes of XML files corruption is seen when there is a filesystem full condition.

2.       If it is not relates to file system space issues, then it might be because of corrupted adapters.os_xml

3.       As additional symptom $DOMAIN_HOME/config/fmwconfig/ovd/default/server.os_xml was detected as zero (0) bytes.

Corruption of the adapters.os_xml or server.os_xml under this LibOVD location file may lead to Weblogic server startup failure.

Please navigate to the fmwconfig folder and check the adapters.os_xml or server.os_xml file or both
$DOMAIN_HOME/config/fmwconfig/ovd/default/adapters.os_xml

There are chances the any of those xml file could be corrupted due to which the Weblogic server fails to start.

4.       In case the file is corrupted, please perform the following steps:

a.       Take a backup of $DOMAIN_HOME/config/fmwconfig/ovd/default/adapters.os_xml  or  server.os_xml

b.      Delete corrupted adapters.os_xml or server.os_xml files under
 $DOMAIN_HOME/config/fmwconfig/ovd/default/adapters.os_xml

c.       Copy adapters.os_xml or server.os_xml from
         $MW_HOME/oracle_common/modules/oracle.ovd_11.1.1/templates/ to
         $DOMAIN_HOME/config/fmwconfig/ovd/default/. Or restore files from backup.

5.        Restart the server. It should works!!

 Hope this post helps you to resolve this issue.
