Cannot sync sentry to the tip.

• Ubuntu 18.04, kernel: 4.15.0-88-generic
• Role sentry, with pruning archive enabled and also tried without
• Other flags: --wasm-execution Compiled

I have tried a purge-chain and tried to resync, but no luck so far.

Could you try latest master? There is a fix for it.
