Yes, we had this kind of stuff in our logs:

Jun 20 08:15:25  cr-co-01-pareq2-re0 rpd[9656]: %DAEMON-3: Prefix Send failed ! x:x:186.177.176.0/23 (label 19) 
bgp_rt_trace_too_big_message:1213 path attribute too big. Cannot build update.

The AS path we have here is currently 12956 262206 262206 262197...
