The node stopped producing blocks at the beginning of the epoch

[narniec]

This morning I noticed that my node stopped producing blocks. I immediately opened the logs and saw the following:

I rebooted the node, but it didn't solve the problem. After deleted folder data /root/.near/betanet/data and it helped
Blocks were no longer produced at the beginning of the epoch (only 1, an hour later, another 1 block)

at the same time my cpu grew sharply

Two questions:

• Did it only happen at the beginning of an epoch?
• How were you sure that your node was not producing blocks?

Two questions:

• Did it only happen at the beginning of an epoch?
• How were you sure that your node was not producing blocks?

• Yes, at the beginning of the epoch. The previous 2 epochs fully received 100% blocks
• I received a notification in my email, I checked "near validators current" and saw my Blocks produced = 0 and i checked logs. I had this problem yesterday, but I thought it wouldn't happen again

[bowenwang1996]

I checked "near validators current" and saw my Blocks produced = 0 and i checked logs

How many blocks were you supposed to produce when you saw there are zero blocks produced?

I think about 30, before that i was on the road

Looks like it is caused by #2806, but it is not clear to me why this only happens to your node. What kind of CPU do you use?

My CPU:
AMD EPYC Processor (with IBPB)

There are 2 more people who have the same problem the last 2 days. They have the same high CPU load. I can find out what processor they , if necessary
1.

2. Intel(R) Xeon(R) CPU @ 2.30GHz

I see. Did they report it anywhere?

No.
They wrote only in the telegram chat RU

@narniec how long does the high cpu usage last?

@narniec how long does the high cpu usage last?

Until I stop the node and delete the data folder. My node works for 2 epochs, after which it does not produce blocks.
I set up another server.
Public_key and account ID a good

Until I stop the node and delete the data folder.

Can you give an estimate in terms of the amount of time or number of blocks?

[narniec]

Exactly two epochs passed, and the node worked well. Now the beginning of the new epoch and in the logs immediately appeared this:

Cpu UP:

How long does this last?

[narniec]

How long does this last?
As i said earlier, until i delete the data folder.
Today i moved to a new server, made everything new, changed the validator key, and check how everything will work. The 3rd epoch is already underway and everything is fine!

I have not encountered this problem again.
