Hi Community,
I have updated my Stakepool to (Core - Mainnet) : 1.29.0 [4c594429] - Alonzo-Upgrade. Furthermore I have lowered from two Relay-Nodes to just one Node and updated the “mainnet-topology.json” accordingly.
Afterwards I have started ./topologyUpdater.sh which shows the error below:
cardano-cli: Network.Socket.connect: <socket: 11>: does not exist (No such file or directory){ “resultcode”: “502”, “datetime”:“2021-09-19 15:32:29”, “clientIp”: “46.101.127.176”, “msg”: “invalid blockNo ” }
Can some one please help?
Furthermore “gLiveView.sh” remains in the “starting” state.
After starting the Blockproducer via “startBlockProducingNode.sh”
it shows error messages after a while:
block-pr:cardano.node.Forge:Error:88] [2021-09-19 15:58:59.00 UTC] fromList [(“val”,Object (fromList [(“kind”,String “TraceNoLedgerView”),(“slot”,Number 4.0500848e7)])),(“credentials”,String “Cardano”)]

Thank you in advance!
With kind regards.
It seems the nodes not started, how is the relay? Still starting? Did u followed coincashew or cntools guide?
Hi Alexd1985,
the relay node exits after quite some time with this error message:
[relay-no:cardano.node.ChainDB:Notice:1116] [2021-09-19 16:08:08.53 UTC] Chain extended, new tip: b4923103534c861b6d793242d86162619d0bc01e84c9a93873a8f134fbf5c253 at slot 39803072

I had a look at the “cntools” tutorial from Coincashew.com
Especially on the “Publishing your Relay Node with topologyUpdater.sh” and on
“How to update a Stakepool” in this case.
RAM issues, u will need more than 8 G; what is the hardware configuration for Relay?
You can test it by set to false the TraceMempool inside the configuration file (and restart the node)
Relay-Node is configured like this:
8 GB / 4 vCPUs
sudo systemctl status cardano-node gives the result below:

Will the Relay Node and the Block-Producer need an RAM Upgrade, or just the Relay-Node?

Hi Alexd1985,
thank you for your help, very much appreciated!
The Pool is working again after I have updated the Relay-Node to 16GB RAM.
Have a nice Sunday!
With kind regards.

You are welcome, glade u fixed

Keep it under monitoring, eventually activate 2-3 G swap MEM; I know my Producer is using more than 8G

Thank you very much for answering my question.
I guess the activation of 2 - 3 G swap MEN is needed in this case.
Guild LiveView v1.20.10 has just lost connection to the Blockproducer Node.
The Relay-Node is still up and running.

Uptime 4 minutes so, u will need to upgrade the RAM or activated SWAP
Hi,
I have created a 3 GB swap file by following this process:
Create the swap file:
sudo fallocate -l 3G /swapfile
Permissions so that only root can write to:
sudo chmod 600 /swapfile
sudo mkswap /swapfile
Setting up swapspace version 1, size = 3 GiB (3221221376 bytes)
no label, UUID=80a9e87c-c78d-4a8b-bd5a-540397f89d70
Activate it with:
sudo swapon /swapfile
sudo echo “/swapfile swap swap defaults 0 0” | sudo tee -a /etc/fstab
cat /proc/swaps
Filename Type Size Used Priority
/swapfile file 3145724 0 -2
I will monitor the stability of the Block-Producer, and update the RAM if required.
Thank you.
