testnet block issue

[glasgowm148]

Problem two separate people reported

eratosthenessieve#8181 I'm also having issues syncing on testnet, where it stops at block id 7feca496e2be164de5cedbb4300031fe1f6189c7029d64eb2f6322707fdf9348. Just took a look at the logs using the commands in the pin, and the most prevalent issues from logs are the following:

1. Stop expecting ae789db2eb855589cafacdaf246c357ece89b204cdda8ae76714f571c2d34ad9 of type 101 due to exceeded number of retries 2
2. java.lang.Exception: Cannot readSecretStorage: dir '/home/user/ergo/.ergo/wallet/keystore' doesn't exist java.net.ConnectException: Connection refused java.net.NoRouteToHostException: No route to host

DreamsMoney#1427 I'm having the same issue on testnet. I've tried from local and cloud machines and it get's stuck on header download - always that exact same block he mentioned "ae789db2eb855589cafacdaf246c357ece89b204cdda8ae76714f571c2d34ad9". I've memorized the header ID at this point lol.

Hello fellas. Apologies for the delayed test data. A few testing results below. I have 3 test nodes, each with different test cases. I'll do a different comment for each.

Node version: 4.0.25-65-f343ebb6-SNAPSHOT (kvsync branch) Command run: java -jar ~/ergo.jar --testnet -c ~/testnet.conf 2>> ergo.log 1> /dev/null & #ergo.jar symlinked to kysync jar RAM/CPU: 2gb, 2 cores - AMD EPYC 7000 OS: 20.04.2 Ubuntu SMP x86_64 x86_64 x86_64 GNU/Linux JVM Version: OpenJDK 64-Bit Server VM (build 17.0.2+8-Ubuntu-120.04, mixed mode, sharing) Storage location: A standard SSD on AWS cloud.

This was a fresh sync using the kvsync branch. It's stuck on header download, header ID: 7feca496e2be164de5cedbb4300031fe1f6189c7029d64eb2f6322707fdf9348 (Note, this a correction to my statement on Discord. This is actually the ID It keeps getting stuck at.)

This was a fresh sync using the current release. It's also stuck on header download, header ID: 7feca496e2be164de5cedbb4300031fe1f6189c7029d64eb2f6322707fdf9348 (Note, this a correction to my statement on Discord. This is actually the ID It keeps getting stuck at.)

This last one is the messiest test case (it's okay if we ignore it as long as I have a syncing method! :)). It's on a local node that was previously synced, now believe's it's synced, but it really isn't anywhere near the testnet's explorer height. I've tried a few node versions + config options to get it to really sync, all with no luck.

Node version: 4.0.25 (latest release) and 4.0.25-65-f343ebb6-SNAPSHOT (kvsync branch) Command run: java -jar -Xmx3G ~/chains/ergo/client/ergo.jar --testnet -c \~/chains/ergo/client/tests/testnet.conf &>> logs/testnode.log & #ergo.jar symlinked to version jar RAM/CPU: 32gb, 12 cores - AMD Ryzen 9 OS: Linux 5.13.0-39-generic #44\~20.04.1-Ubuntu SMP Thu Mar 24 16:43:35 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux JVM Version: OpenJDK 64-Bit Server VM (build 11.0.14.1+1-Ubuntu-0ubuntu1.20.04, mixed mode, sharing) Storage location: Local NVMe SSD WARN|ERROR log: ergo-testnode3-error-warn.log

At one point I ran the node with config offlineGeneration = true. I also tried knocking some syncing sense into it with config headerChainDiff = 80 as documented, but didn't have any luck.

One final test case I happened to run. The following is an attempt to sync from scratch with an earlier ergo node version, 4.0.23. It got stuck on the same block - "7feca496e2be164de5cedbb4300031fe1f6189c7029d64eb2f6322707fdf9348"

Node version: 4.0.23 Command run: java -jar ~/ergo.jar --testnet -c ~/testnet.conf 2>> ergo.log 1> /dev/null & #ergo.jar symlinked to 4.0.25 jar RAM/CPU: 2gb, 2 cores - AMD EPYC 7000 OS: Amazon Linux 5.10.102-99.473.amzn2.x86_64 x86_64 x86_64 x86_64 GNU/Linux JVM Version: OpenJDK 64-Bit Server VM Corretto-17.0.2.8.1 (build 17.0.2+8-LTS, mixed mode, sharing) Storage location: A standard SSD on AWS cloud.

This is another test with the same occurrence, but this time with the EIP27 branch. I significant difference is that this exact same machine got stuck while it was public, using the config below, but making it unpublic with everything else the same - produced a fresh sync.

ergo { networkType = "testnet"

directory = "/home/ec2-user/data" node { mining = false } wallet.secretStorage.secretDir = "/home/ec2-user/data/wallet"

} scorex { restApi { apiKeyHash = "..." } network { peerDiscovery = false } }
