[tipc-discussion] Tuning/Debugging of "Retransmission failure"

[Duzan, G. D <Gar...@fi...>]

   I've started to notice messages like this when pushing TIPC a bit:

[Wed May 15 11:27:32 2024] tipc: Retransmission failure on link <xxxxxxxxxxxx:deb03-yyyyyyyyyyyy:ubu06>
[Wed May 15 11:27:32 2024] tipc: State of link  Link <xxxxxxxxxxxx:deb03-yyyyyyyyyyyy:ubu06> state e
[Wed May 15 11:27:32 2024] tipc: XMTQ: 15 [30965-31149], BKLGQ: 0, SNDNX: 31150, RCVNX: 27685
[Wed May 15 11:27:32 2024] tipc: Failed msg: usr 12, typ 0, len 13928, err 0
[Wed May 15 11:27:32 2024] tipc: sqno 30965, prev: ace568c, dest: ad7f568c
[Wed May 15 11:27:32 2024] tipc: retr_stamp -1697900680, retr_cnt 73

The host reporting the problem is running:

Linux vlltcgtmdeb03 6.7.9-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.7.9-2 (2024-03-13) x86_64 GNU/Linux

and the other end of the link is:

Linux vlltcgtmubu06 6.5.0-27-generic #28-Ubuntu SMP PREEMPT_DYNAMIC Thu Mar  7 18:21:00 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

Is there any tuning I can do to avoid the problem, or other data to collect to better understand it?

   Thanks.
