Rippled: Rippled syncing issues

[lrauldan]

Hello,

I built rippled on a dev server, running ubuntu 16.04. Whatever I do, I can't seem to get rippled to sync the ledger.

I'm not sure what I'm missing but here are the environment specifics:

/etc/rippled/rippled.cfg

[server]
port_rpc_admin_local
port_peer
port_ws_admin_local
#port_ws_public

[port_rpc_admin_local]
port = 5005
ip = 0.0.0.0
admin = 0.0.0.0
protocol = http

[port_peer]
port = 51235
ip = 0.0.0.0
protocol = peer

[port_ws_admin_local]
port = 6006
ip = 127.0.0.1
admin = 127.0.0.1
protocol = ws

#[port_ws_public]
#port = 5005
#ip = 127.0.0.1
#protocol = wss

[ips]

You're coming very close to the minimum recommended amounts on your server. Please see the links below.

https://wiki.ripple.com/Latest_rippled_release_notes
https://developers.ripple.com/capacity-planning.html

This recommends 8 GB or more RAM.

The ledger grows at 5 GB per day as of Q4 2015, so you may also be pushing the edge of your storage space. In Ubuntu run

df -h

To see how much you're currently using.

@antechdemo, my machine has 16 GB of ram and the storage availability is 2.9T.

As for the average load, it is constantly under 4 ( my machine has 4 cores ).

You can try switching to RocksDB.

Stop the server (ctrl+c)
Edit rippled.cfg, updating the [node_db] stanza. Example:
[node_db]
type=RocksDB
path=/efs/.config/ripple/db/rocksdb
open_files=2000
filter_bits=12
cache_mb=256
file_size_mb=8
file_size_mult=2
advisory_delete=0

You may notice that your server does not have _any_ peer connections. Without a connection to the network, it can't possibly sync.

The reason it has no peers is a consequence of your configuration (specifically, you have [peer_private] set to 1, which means your server won't attempt to establish any outgoing connections, which it warns you about on startup).

Unless you have a specific reason to limit the servers to which you connect, I would recommend removing the following lines from your config file:

[ips]
54.84.21.230 51235
54.86.175.122 51235
54.186.248.91 51235
54.186.73.52 51235
184.173.45.38 51235
198.11.206.26 51235
169.55.164.29 51235
174.37.225.41 51235

[peer_private]
1

Furthermore, you should remove the following lines from your validators.txt:
