Problem

All XLayer nodes (mainnet and testnet) were crash-looping with the following fatal error on startup:

Fatal: /config/geth.toml, line 12: field 'XLayer' is not defined in gasprice.Config

Root Cause

XLayer migrated from Polygon CDK (zkEVM) to OP Stack on Oct 27, 2025 (Jovian fork). The geth.toml config files in op/xlayer/{mainnet,testnet}/ still contained the old [Eth.GPO.XLayer] section with Kafka-based gas price oracle settings from the CDK era:

[Eth.GPO.XLayer]
Type = "follower"
UpdatePeriod = 100000000000
Default = "100000000"
KafkaURL = "localhost:9092"
Topic = "middle_coinPrice_push"
GroupID = "geth-consumer"
L1CoinId = 15756
L2CoinId = 7184
DefaultL1CoinPrice = 2000.0
DefaultL2CoinPrice = 0.5
Factor = 0.1

This section was explicitly removed in op-geth v0.1.4 (okx/op-geth PR #168, Feb 9, 2026), which deleted the entire gas price controller. The current xlayer/op-geth:v0.1.4 binary no longer recognizes these fields, causing the fatal crash.

Affected Hosts

rpc-de-27: xlayer-mainnet, xlayer-testnet
rpc-us-32: xlayer-mainnet

Fix

Removed the entire [Eth.GPO.XLayer] section from both op/xlayer/mainnet/geth.toml and op/xlayer/testnet/geth.toml. Added MinSuggestedPriorityFee = 1 to [Eth.GPO] per the official XLayer toolkit reference config.

Updated config:

[Node.P2P]
DiscoveryV5 = true

[Eth.GPO]
Blocks = 20
Percentile = 60
MaxHeaderHistory = 1024
MaxBlockHistory = 1024
MaxPrice = "5000000000000000000000"
IgnorePrice = "2000000000000000000"
MinSuggestedPriorityFee = 1

Resolution

Commit: 2f841387
All three nodes confirmed syncing after deploying the fix via run-rpc-update + Compose up
