Pruned or corrupt world state > Shutdown due to a VM fatal error. #1162

Open AionMiner opened 3 years ago

AionMiner commented 3 years ago

Description

Since v1.6 cannot keep SPREAD node alive, non-graceful shutdown occurs then having restarting (due rocksDB lock) and reverting several thousand blocks, node will be in sync for some hours before non-graceful shutdown occurs again (observed 3 times over 3 days).

Have since swapped to FULL node and no issues.

I'm running:

AionJayT commented 3 years ago

@AionMiner Thanks for the issue report. We will investigate the issue. There is another mode called "TOP", it also saves DB spaces (Not like SPREAD mode, always prune the data, TOP mode keeps the full DB state of the top few hundreds block then prune it), if this node runs well. I think you can switch to this mode.

AionMiner commented 3 years ago

Have switched to TOP mode, working well 👍

AionMiner commented 3 years ago

Have encountered similar issue with TOP mode today (fresh 1.6.2 install, sync db from genesis online for ~3 days before issue).

Kernel was running fine until block height 7446583, then kernel outputs wall of WARN logs. ctrl+c graceful shutdown was successful but am now unable to get kernel to launch, attempted revert DB but similar notice as previous.

@AionMiner The WARN log of the Transaction is fine. Someone sent the invalid transaction to the network so has been reverted. You can set the logger Level to ERROR in the TX category or remove the category if you don't want to see the transaction log. For the revert issue in the TOP mode. Yes, I can duplicate it. So I think the revert currently won't work for the TOP mode.

Do you still have the log when you see the launching issue when you wad shutting down the kernel at 7446583?

AionMiner commented 3 years ago

@AionJayT The WARN log was repeating itself over hundreds of thousands of lines, there was many log files created just full of the WARN notices and nothing else.

I noticed the TOP node out of sync from the connection to my FULL node and logged in to find the kernel just spitting out those WARN notices before I manually shut it down.

The launch log starting at 20-12-18 07:25:30.498 was directly after the actions: shutdown, launch (constant WARN logs again), shutdown, revert to 7440000 (reported success), launch (exception).

Unfortunately I no longer have access to the logs but I will spin up another server and see if it reproduces.

AionMiner commented 3 years ago

Has been over 10 days of uptime and TOP mode kernel has yet to reproduce the sync halt issue experienced previously. However, there's been no invalid block/tx logged since becoming fully sync'd (since block 7464349 till now 7550424).

I suspect the invalid block/tx event is what lead to the previous sync halt, being that the kernel was still running yet out of sync for ~7 hours (since the invalid block) with the only output whilst in this state being invalid block/tx WARN CONS until I intervened with shutdown.
