Hello everyone.

I am running Asterisk on the hardware / software platforms described above in 3 different branches of the company I work for. One server per office, all of them pretty much alike regarding hardware and software configuration.

This started a few months ago, every server keeps alarming and showing this log message:

Severity      : Critical
Date and Time : Mon Mar 24 09:02:21 2014
Description   : A bus fatal error was detected on a component at slot 5.

This is referring to the slot where Sangoma Card is installed. It gets worse when one of the server keeps rebooting almost 2 times per day due to this, which is dangerous and worktime loss.

I also provide here my MFC/R2 and DADHDI configuration and below the logs regarding the errors just before the server rebooted.

I look forward to your helpful comments or further questions.
Thank you in advance

Best regards.
