The problem was in the software generating the installer. We have worked with their team and they have been very responsive.

The problem has been fixed with the release of a new installer version (Less than one day, about 12 jours :-):
Version: ejabberd-1.1.1_2-linux-installer.bin
Download page: http://www.process-one.net/en/projec....html#binaries

Note that the problem was not on ejabberd itself but on its installer generation tool, which is a third-party installer generator software.

Best regards,
