There have been few instances of Cortex on RHEL 4 servers that have issues loading the FTP service. If you are restarting cortexd, you will not see the error messages.
However, if you run:
/usr/local/i365/bin/indiftpd
You may get the following output:
/usr/local/i365/bin/indiftpd: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory
In order to fix this issue you will need to run the following command to rectify the library issue:
up2date compat-libstdc++-296 compat-libstdc++-33
Then to restart Cortex ftp you will need to use the following command:
/etc/init.d/cortexd restart
