Hi Bill, This is very interesting.
A couple of questions (#4 is the important one): 1) What version of VxWorks are you using? Is this VxWorks 6.3 or VxWorks 6.4? 2) What are the TIPC buffers set to (parameters TIPC_DATA_00064 through TIPC_DATA_65536)? 3) I am assuming you are running over Ethernet with MTU=1500? Or are you using Jumbo frames? 4) When you say you get the error and the data reported by WireShark looks OK, do you mean that the data is correctly received on the other node just that the sender registers an error? If the data is getting through alright to the other node, then it could be that the buffer pool management system indicates an error for the size you are sending but then TIPC allocates space off the heap and continues. Try increasing the value of TIPC_DATA_16384 which is probably 0 right now. Many of the values of these parameters were left at 0 since they are fairly application dependent and any large packets will be allocated as needed. But if the application is constantly using large packets, then pre-allocating them by setting the buffer parameters will be faster overall. Let me know how it goes.

I'm seeing errno 0x730002 (S_netBufLib_CLSIZE_INVALID) when I attempt to use sendto to transmit 12524 bytes of data using a socket with a family of af_tipc, and a mode of sock_rdm. When I look at the tipc and netStack pool show output, I do not see anything suspicious, and the data as reported from WireShark looks OK. I was under the assumption that I could use this approach for sending datagrams as large as 15000 bytes. Is that not the case?
