I had a similar problem a while back. Here is the response that I reveived from Cisco TAC.
The second port on a 2 T1 VWIC will have to be set to clock source internal because the 2 port VWIC has a single common clocking chip in it. Two clock sources to each of the ports on the same VWIC will result in slips.
Set the second port to internal, on both vwics. This will fix it.

Hai Clifton,
Thanks for the reply,This is a multilink with 5 E1 MPLS connnectivity.ISP had shared the Error report in PE router...no erros observed in their sonet (for 5 KLMs)...both end clock source is line.. SDH is generating the clock ...in this case any suggestion .so just one more confirmation can i change the clock source to internal for second port ???
kindly reply

Yes, you can change the clock source to internal for the second port. The configuration is done under the controller config.
