[asterisk-users] kernel: dahdi: Master changed to TE2/0/2 --- Is a normal message
I have a server with an asterisk ss7 link connected to a Siemens working well for over a year. A few days ago I started having problems with signaling. I found the following logs in / var / log / messages Sep 12 11:49:25 call3 kernel: [1018427.030959] dahdi: Master changed to TE2/0/2 Sep 12 11:49:25 call3 kernel: [1018427.120740] dahdi: Master changed to TE2/0/1 Sep 12 11:49:26 call3 kernel: [1018427.789173] dahdi: Master changed to TE2/0/2 Sep 12 11:49:26 call3 kernel: [1018427.884828] dahdi: Master changed to TE2/0/1 Sep 12 11:49:29 call3 kernel: [1018431.209621] dahdi: Master changed to TE2/0/2 Sep 12 11:49:29 call3 kernel: [1018431.300289] dahdi: Master changed to TE2/0/1 Sep 12 11:49:33 call3 kernel: [1018434.763742] dahdi: Master changed to TE2/0/2 If I stop the asterisk and dahdi driver just let the messages continue to appear. Any ideas?? -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.digium.com/pipermail/asterisk-users/attachments/20120912/e02cfd58/attachment.htm>

Each time it goes into alarm the core of DAHDI will look for a new span to use as a timing source for asterisk. If TE2/0/1 is the "preferred" timing source, when it comes out of alarm, DAHDI will switch the timing back to it. -- Shaun Ruffell Digium, Inc. | Linux Kernel Developer 445 Jan Davis Drive NW - Huntsville, AL 35806 - USA Check us out at: www.digium.com & www.asterisk.org

Sorry, in the last line I try to say ... With asterisk stopped, and only driver dahdi up, messages still appear...
