Hello. I have mentioned previously that I experienced nodes crashing and I was asked to get more logging information. I had the crash again today, with 3 out of four nodes crashing in relatively quick succession and am posting the log files in case there is something that you recognise on it

Besides the stack trace, the intermittent errors that I see in my log file:
ERROR exonum::events::error] An error occurred: peer 0.0.0.0:2000 disconnected
(At the very top of the first log file above). These seem quite strange - why is
0.0.0.0:2000 seen as a peer? And why would it seem to be connecting to itself?
I use the helpers to create my config files, which have this setup:
consensus_public_key = "1532a25e2481623938ab6dc001988851d32056e3b0b6bb3c3db870f19048b37d"
consensus_secret_key = "/config/consensus.key.toml"
external_address = "node2.abc.com:2000"
listen_address = "0.0.0.0:2000"
service_public_key = "31169e28fb3dc29e65ae8825dff635bb06be459fafe88cf128443bdbe4633fa0"
service_secret_key = "/config/service.key.toml"
[api]
private_api_address = "0.0.0.0:8010"
public_api_address = "0.0.0.0:8000"
state_update_timeout = 10000
[[connect_list.peers]]
address = "node4.abc.com:2000"
public_key = "0f20ad34a3ee830a323a07e3f6bb51a8030c72e72fc7caadae21df349f4a207e"
[[connect_list.peers]]
address = "node3.abc.com:2000"
public_key = "30ce1435d6175f085beda1027cc6189cef9af65eebbae8c8c6dbc42ff8a79627"
[[connect_list.peers]]
address = "node1.abc.com:2000"
public_key = "c08cd95a8d9c3ac1737b4d835d0e8c77cc57ca9665cad990944cdc18c34bb1c5"This is the config for node2.abc.com, of a 4 node network that includes node1.abc.com, node2.abc.com, node3.abc.com, node4.abc.com. All other nodes similarly have 3 peers with listen_address set to 0.0.0.0:2000 and external_address as their FQDN
Does anything jump out in these log file / config file snippets?
@VadimBuyanov , we don't have such tool in public access so far
Hello everyone!
I'm trying to add an auditor node to a running network, and I cannot quite get it right. Can you help with that?
I use the timestamping example as the basis, so it can be used to reproduce the error.
After bringing up 4 validators with launch.sh script, I configure a new node the same as the validators:
./app generate-config config/common.toml config/a --peer-address 127.0.0.1:6335 -n
./app finalize --public-api-address 0.0.0.0:9000 --private-api-address 0.0.0.0:9001 config/a/sec.toml config/a/node.toml --public-configs config/{1,2,3,4}/pub.tomlThat should result in a config for a node that's not in the list of validators, i.e it should act as an auditor (to my understanding)
Then, I start the new node up (with all validators in peer list)
./app run -c config/a/node.toml -d config/a/db --consensus-key-pass pass --service-key-pass passThat's when the strange things start to happen: a lot of errors on every node in the network and connection failures
Validator nodes log: https://pastebin.com/zrsUaKj3
New node log: https://pastebin.com/i1c9U3AM
@mersinvald, try to add auditor's address and public key to peer list of every other node via API https://exonum.com/doc/version/latest/advanced/node-management/#add-new-peer
@ivan-ochc thanks, I already figured it out after patching exonum error handling a bit.
When you add a context to the error -- you somehow lose the error itself, so I have only seen the context in the logs, not the error itself.

Hello, are there docs or guides on advanced node creation? I'm using NodeBuilder and it seems like when I throw too many transactions at it, it starts getting backed up. I'd like to adjust the max
tx_pool_size (which seems to be at 0 at all times during my testing) and having trouble finding how this would be done.
So what happens is I have a simulator that is sending test transactions to the node. It works great at first,
tx_count grows steadily, but after a few minutes tx_count stops growing even though I am throwing transactions at it constantly. At this point I would expect (maybe?) to see tx_pool_size grow beyond 0 but it stays there and then the requests to grab transaction information start to time out (they have a 30s timeout).
So it seems like something is blocking new transactions from being entered. I am probably running about 40-50 transactions/second against a quad core machine (CPU/mem are not being saturated)
I tried setting
[mempool]
tx_pool_capacity = 5000 in my node config but it didn't seem to change anything
can someone pls look into this?
Hello @utkarshkvs1. Did you use this script https://github.com/exonum/exonum/blob/master/examples/cryptocurrency-advanced/docker/launch.sh ?
@aleksuss
@utkarshkvs1 create an issue on github please. And don't forget to attach log output.
Hi everybody, i started working with exonum last week and plan to use it in a commercial product. Right now, our team of 2 is developing a poc and managed to get the Crypto Advanced tutorial up and running. We are working with 0.12.1 and i am trying to integrate a simple java app via java light client. However, i always get an error 'Wrong PublicKey size'.
All i am doing is creating the transaction (protobuf builder), building a signed TransactionMessage and then using 'exonumClient.submitTransaction(transactionMessage)' to send it.
I am able to pull the authorKey out of the message and verify the signature, so it seems to be a configuration issue in the node.
However, my colleague was able to send a test transaction from within rust, so the basic functionality is given.
Thanks in advance!
