System information

Geth version: geth_linux version 1.3.5-fe928d47-20231208
OS & Version: Linux

Expected behaviour

Sent transactions are broadcasted properly.

Actual behaviour

Once every several months we have issues with broadcasting transactions.
It has happened across multiple versions of 1.2.x and now we've noticed that issue on 1.3.5.

After 3 days of proper work and multiple transactions being sent BSC stopped broadcasting transactions.

In logs transaction submission is visible, but nothing more happens:

t=2023-12-17T16:27:29+0000 lvl=info msg="Submitted transaction"                  hash=xyz from=xyz nonce=xxx recipient=xxx value=0                      x-forward-ip=nil

I was able to send the same transactions (RAW hex) through our other nodes (as well as using bscscan.com). So it's not a wrong gas price estimation.

After restarting geth - everything works fine again - transactions are sent and broadcasted correctly.
Before restart geth had 66 connected peers (and the same number after restart), so it's probably not a connection problem.
