The big problem is HDLC Abort(6) / HDLC Bad FCS(8) / MTP2 link down
(SLC 0). And this is the source.

not the " Unable to write frametype: 2", this is only effect.

Too much work on CPU on this box? Try to disable any software
cpu-intensive tasks like transcoding, dtmf detection, software EC
etc...
or put rxt1 (Rhino channel bank or sth?) to another CPU like CPU1 ?
