Hey,
I have a slight problem with my relays after the 1.29.0 update.
It seems that it was initially working with tip node and reference all okey, an processed TX.
But then the relays are losing in/out peers over time and eventually lags around 8/9 in/out peers.
I try to restart the nodes but they work for the first minute then they go out of sync.
Any help would be much appreciated before the HFC.
Thanks!!

Please check your logs if the node is restarting. Also, check for any errors. How much RAM do you have?

Hey @mcrio . Thanks for the reply. I have 16 GB RAM and the topology updater is not syncing because of incorrect block slot

Any errors in the logs? journalctl --unit=cardano-node -n 250 | grep -i Error

Also check how much uptime you have, whether the service may be restarting: systemctl status cardano-node

Please verify the time on your server is correct.

Yeah the time seems correct. Its weird… I have been trying to figure it out, but seems like the peers seem to be dropping off. Maybe the topology updater is not functioning properly for me?

According to the error it seemed like your server time is lagging behind… It’ll fail even if its 10sec off…

What does chronyc tracking
output?

According to chrony documentation:
If the reference ID is 7F7F0101 and there is no name or IP address, it means the computer is not synchronised to any external source and that you have the local mode operating (via the local command in chronyc , or the local directive in the configuration file).
I assume you have a system clock issue. Try resolving chrony or try manually syncing time from an NTP server and see if that will do it.
