I want to discuss a recent issue we've discovered at BitCanna MainNet with some Go RLY (v2.4.x)
We have (at least) 3 relayers' providers that use Go Rly (v2.4.0 and v2.4.2)

Relayed By ...... | rly(2.4.2)
Relayer by ...... | rly(2.4.0)
Relayed by ...... | rly(2.4.2)

They are the most "active" here:
https://relayers.smartstake.io/network/BCNA

And we can observe that IBC client update & IBC ACKs are sent in loop every 30 seconds (and 15 seconds) for send_TXs that maybe were sent 17h ago (even 24h ago)

Logs are "normal" we see a loop of UPDATE client and ACK

This behavior stops when they restart the rly daemon, but starts later again.
