I've seen a similar problem before. Span 3 was throwing errors for
(what seemed to be) no reason at all. After some testing it seemed
that the number of errors thrown on Span 3 had a relationship to the
temperature inside the servers. After installing additional cooling
the errors had reduced significantly IIRC. This was across numerous
servers each having 2 Digium quad T1/E1 cards in them.
May not be the same story in your case but try cooling the server and
see if that helps some.

This afternoon I finally figured out more with regarding to a strange
clock-slip problem we have on our asterisk box.
We have two TE410s, in E1 mode:
TE410P version c01a009b
They have their own interrupts:
66: 781648298 783747388 IO-APIC-level t4xxp
233: 253890977 1311504670 IO-APIC-level t4xxp
They have their full 31 channels:
span=3,0,0,ccs,hdb3,crc4
bchan=63-77,79-93
dchan=78
span=7,0,0,ccs,hdb3,crc4
bchan=187-201,203-217
dchan=202
And properly configured in zapata:
group = 3
context=unused
switchtype=national
pridialplan=unknown
prilocaldialplan=unknown
signalling = pri_net
channel => 63-77,79-93
group = 7
context=unused
switchtype=national
pridialplan=unknown
prilocaldialplan=unknown
signalling = pri_cpe
overlapdial=no
channel => 187-201,203-217
And on them, both the span 3 interfaces gives huge amount of HDLC
errors in the logging and clockslip-ticks on the line. Juggling the
cables between other interfaces, and the then-non-span-3 is clear
and the new-span-3 is full of HDLC errors and clockslips.
Myself I'm going with a "this must be hardware problem", unless
somebody else has an idea.
