Thanks Rafael, I checked the log and it seems to be the DNS problem. I updated the DNS and restart the server. Now I have the call fundtion come back.
But an error message keep pop up as
"An error occurred while loading or saving configuration information for Gecko. Some of your configuration settings may not work properly."
click the detail is says
"Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See
www.gnome.org/projects/gconf/ for information. (Details - 1: IOR file '/tmp/gconfd-root/lock/ior' not opened successfully, no gconfd located: No such file or directory 2: IOR file '/tmp/gconfd-root/lock/ior' not opened successfully, no gconfd located: No such file or directory)"
Can you direct me what's wrong here? /tmp/gconfd-root/ is empty. How can I fix this?
Appreciate for your help.
