kernel: dahdi: Detected time shift

[stefano.pucci]

Hi all,

my environment is on VMWare :

OS : CentOS release 5.10.1 (Final)
VERSION: 2.12-493a
BUILD: 150703-2105
© 2015 ViciDial Group
Asterisk : 1.8.23.0-1_centos5.go

We're experiencing some issues on agents disconnection(all agents simoultanoeusly).
I take a look on my /var/log/messages and it shows :

kernel: dahdi: Detected time shift

I re-run ntpdate because my date commend showed that my VM is 2 minutes back to the real hours.
Could you please give me if you have already troubleshooted this kind of problem?

Thanks
Stefano

One more info, I've seen on CLI Asterisk during the disconnection :
NOTICE[4986] chan_sip.c: Disconnecting call 'SIP/XXXXXXXXX' for lack of RTP activity in 113 seconds

It's not going to be a solution, but, why don't you just download latest VICIDIAL 7.0.4 and start from there ?

Take care and good luck

"for lack of RTP activity" is usually a network issue introducing one way audio usually by a NAT issue. Or someone just closed their soft-phone.

Dahdi does not run well in a VM, don't virtualize Asterisk meetme -it won't work as expected.
