Syncing Issue

[m-e-r-k-l-e-root]

1. What did you do?

Attempt to start/sync tron full node (Great Voyage - v4.1.1)

2. What did you expect to see?

Successful block syncing.

3. What did you see instead?

/logs/tron.log fills with java exceptions, along with errors in which indicate peer connection has been closed, etc.

i.e.

my tron.log file consists of primarily errors such as the following:

along with errors that look like:

09:31:08.631 INFO [TronJClientWorker-4] [net](TronChannelInitializer.java:48) Close channel:/161.117.184.66:18888 | 8099a6785ad391664a56d7bc4ec1ab5ee9579be7149c6c6d89165ff23afee0e416f91cf7b78d7c2aed665f52241ac02be4c506ac4f861622263607265c16fc58 09:31:10.393 WARN [TronJClientWorker-5] [net](PeerClient.java:58) connect to 47.242.229.146:18888 fail,cause:connection timed out: /47.242.229.146:18888 09:31:10.394 INFO [TronJClientWorker-5] [net](TronChannelInitializer.java:48) Close channel:null | <null>

• I am using this config file: config.conf
• all ports java-tron requires to be opened are open (i.e. UDP port 18888, etc., etc.)
• tried increasing minTimeRatio to 25.0+ in config
• added a few nodes to the active [ ] block in config

nothing seems to be working.

here is my full /logs/tron.log file: tron.log
and here is the exact config file I'm using: config.conf

system specs:
3 TB SSD
16 Cores
Bandwidth 500M
32GB RAM

any help would be appreciated, thanks!

I've managed to resolve the issue. It was an issue with the machine I was using rather than java-tron itself. Running smooth like butter!

I got it done, the jdk environment is wrong, only version 1.8 can be used.
