6. Known Problems and Limitations

  1. Upgrade may fail when httpd was not stopped before the upgrade.
  2. Installation of the nsim-postnuke package fails on x86_64 architecture.
  3. Parallels Pro Control Panel cannot be installed on FC 6/ FC 4/ RHEL 5/ RHEL 4/ CentOS 5.0/ CentOS 4.4 systems enabled with SELinux.
  4. Creating sub-folders under the Inbox folder, using the email client Microsoft Outlook, fails with an error. This is a known limitation with the email client Microsoft Outlook.
  5. Parallels Pro Control Panel supports the Python version that is packaged with the operating system you install on the server. You can upgrade Python to updates released by the operating system at any time, however, you must not upgrade Python to a version that is not supported by the operating system you installed on the server.
  6. Parallels Pro Control Panel does not support InnoDB tables with MySQL databases. Importing sites that have InnoDB tables causes the process to fail with errors.
  7. Attempts to add or update the zone records created manually using the Add New Zone option (Zone List page) in Parallels Pro Control Panel fails returning the user to the DNS configuration page.
    Solution: To resolve the issue, log in as the root user to the Parallels Pro Control Panel server, and restart the BIND service by running the following commands:
    rndc reload
    service named restart
  8. Parallels Pro Control Panel fails to upgrade SpamAssassin version 3.0.1 (installed by default with RHEL 4/ CentOS 4.4) to the required version 3.0.3.
  9. The Parallels Pro Control Panel services fail on FC 6 servers, because of dependencies issues of the kernel-xen RPM. Solution: To resolve the issue, ensure that the virtualization option is not selected while installing Fedora Core 6.
