- In this case we saw that under /usr/TKLC/ipfe/gui/wsdl there was an invalid soft link created that was pointing to itself. This was triggering the above errors in /var/log/messages

[admusr@dsrSO] ]# ls -l /usr/TKLC/ipfe/gui/wsdl

lrwxrwxrwx 1 root root 27 Apr 2 14:43 wsdl.xsd -> /usr/TKLC/dpi/wsdl/wsdl.xsd

Solution

As a workaround it is recommended to remove this symbolic link

wsdl -> /usr/TKLC/ipfe/gui/wsdl

[admusr@dsrSO Ipfe]# pwd

/usr/TKLC/dpi/wsdl/Ipfe

[admusr@dsrSO Ipfe]# ls -l wsdl

lrwxrwxrwx 1 root root 23 Apr 6 14:23 wsdl -> /usr/TKLC/ipfe/gui/wsdl [admusr@dsrSO Ipfe]#

[admusr@dsrSO Ipfe]# rm wsdl

[admusr@dsrSO Ipfe]#

After removing this extra soft link reports should start to export.
