Applications not loading

Hi

We’ve been using bristuffed * on a live basis for about 4 years, most recently 1.2.26. Recently spontaneously the system failed - calls could not be made though SIP phones could register.

This was tracked down to not all applications, including things like Dial, not being loaded. Show Applications shows

The modules did including things like app_dial. Rebuilding and then upgrading to 1.2.9 resulted in the same - no change. We moved to a standby * server which works fine.

Checked asterisk.conf on the working server and bad one - no differences. Rebooting of course was tried and had no effect. So I still cannot get all functions loaded on the main server.

Anyone any ideas on this? I though that all applications were loaded from the modules folder. Needless to say I cannot fund any error messages when * starts. Help is welcome.

Thanks
