[asterisk-users] kernel: dahdi: Master changed to TE2/0/2 --- Is a normal message

[equis software]

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??
