I was trying to figure out on that issue and find a something
reasonable and I found it.
As of branch 1.4 of zaptel, the option for hardware HDLC framing has
been integrated and IIRC since 3.2.2 version, wanpipe uses it rather
than their own patch, so it's needed to change all those ...
dchan=16
... from zaptel.conf to ...
hardhdlc=16
... in order to pass the HDLC framing from the Sangoma's HDLC engine
to the D channel.
That explains why when you changed version prior the mentioned above,
everything worked (Considering that this thread is from Oct 1, 2007)

Since 2008-03-08, (chan_zap revision #106945) you will see that just
once because the channel state itself is not changing.

Those messages indicate that layer 2 is trying to reinitialize because
there are no response from the other side due the missing working
D-Channel.
