Problem with Dahdi

Asterisk Asterisk Support
1

Hi Asterisk folk,

I have an ubuntu server with asterisk packages from the repos and I have just added a wctdm24xxp card with FXS modules… now I have lots of this message coming up in the logs:

WARNING[2375] chan_dahdi.c: Read failed with -1: Invalid argument

This is accompanied by very high CPU and ram usage essentially bringing the server to a grinding halt…

I am using asterisk 11.7.0 on ubuntu 14.04.3

I am not sure what info to provide to help with this issue and googling the error gives no results that seem relevant to my issue. Any suggestions please?

Many thanks,
Ed

First, stop Asterisk from auto-starting, so you can examine the issue without locking up the box.

Then try to get DAHDI working before Asterisk. There are some binaries prefixed with dahdi_* that can help.

And you might want to double-check your configuration in /etc/dahdi/ directory.

Once DAHDI is up, then start Asterisk manually.
