Prysm: Validator requesting future slot attestations

[SpyderChristian]

🐞 Bug Report

Description

Validator started giving messages

 time="2020-08-04 20:51:47" level=error msg="Could not request attestation to sign at slot" error="rpc error: code = InvalidArgument desc = invalid request: attestation slot 3558 not within attestation propagation range of 2326 to 2358 (current slot)" prefix=validator pubKey=0x881525ad8f18 slot=3558"

Both Beacon, and (geth)Eth1 node were working properly

Has this worked before in a previous version?

First time using prysm

🔬 Minimal Reproduction

Multiple ppl have reported the same problems I cannot recreate it but It fixed itself after stopping and restarting the validator.

🔥 Error

🌍 Your Environment

Ubuntu Server 20.04 LTS

What version of Prysm are you running? (Which release)

alpha 18

Anything else relevant (validator index / public key)?

I am running 120 validators from this public key 0xb3B6C4F33bE7E1e4cadC404adBD7dA54982A00d2

Attestations were missed in Epoch 72, 73, 74 and started working again after restarting the validator.

[KryptoMaton]

I had the same issue on Windows 10. Hardware: i7 2.8Ghz, 8GB ram, 40gb free in ssd. Running alpha 18 on beacon and validator.

Beacon client was working normally when validator attempted to attest with future slot. Validator had been attesting normally before that block.

This might be related but I'm getting blocks from the future on the beacon node side

[2020-08-05 00:38:50] WARN sync: Rejecting incoming block. blockSlot=3793 error=could not process slot from the future, slot time 2020-08-05 04:38:44 +0300 EEST > current time 2020-08-05 00:38:49.872101117 +0300 EEST m=+13720.928452318

Current slot was 2594

[bvukich]

I experienced similar errors simultaneously on three different validator nodes. I restarted one of the nodes and the error occurred again on that node a few minutes later. I restarted my beacon nodes and the error has not returned.

CentOS Linux release 8.2.2004 (Core)
4 cores 16GB 128GB Hybrid VSAN
VMWare ESXi 7.0
Alpha18

Here's a 15-minute slice of logs from each of my validator nodes.
