[Bug]: Validator crashes on failure to obtain list of disabled validators on Kusama block #25830930 #2280
Comments
Thanks for reporting! |
Thanks for the swift attention to the issue!
Unfortunately, get the same error on #2281 after rebuilding db (from #2271 - #2278 wasn't built on it). Attached are logs both for validator & non-validator modes. |
@Lederstrumpf we are investigating the issue. Meanwhile, you may try to sync the node with Warp or Fast sync. For some of our devs problem is not reproducing after they synced to the end of the chain. |
Thanks, fwiw, the Full sync from my backup db from 14 days ago (mentioned here: #2276 (comment)) failed today on the same block/error. Just restarted with a Warp sync from genesis - will update on its result once completed. |
Unfortunately also fails: strictly on the successor of the warp sync target block, both for validator and non-validator modes: Nov 21 10:23:10 v1-oslo kagome[993246]: 24.11.21 10:23:10.547760 main_runner Warning Synchronizer Block #25874041 (0x521d…627b) and 104 others have been discarded: N6kagome10blockchain14BlockTreeErrorE(9) the requested block header is not found in block storage

Sorry, I couldn't find Also, btw the issue from could have been resolved in the master by #2285 . You may try to use master branch to check if it moves forward. (Please note we recently updated the database format, you might require |
Ah, you're right I forgot to attach - sorry about that, here they are:
Will give it a shot - I didn't have #2285 in yet. DB's already migrated though. |
Unfortunately still fails for me with #2285 included; even on a fresh Warp sync, see attached logs. It might be that Amforc's "The Spammening" happening atm is a factor. kagome_warp_sync_fresh_6_validator_#2280.log |
I couldn't reproduce the issue exactly. I suspect there might be some undefined behaviour either with 1) wabt instrumentation or 2) wasmedge . To check 2) please try to rebuild KAGOME with |
Hi Kamil, sorry for my late response. I've applied your two suggestions and get the following issue as the kagome node compiles the wasmedge wasm module - seems it's skipping compilation of a required object file:
Have a suggestion how to get past this? |
Bug Summary
Validator crashes instantly when processing block #25830930 (0x145a…36bc) on Kusama
Bug Description
Validator crashes instantly when processing block #25830930 (0x145a…36bc) on Kusama, presumably due to inability to obtain validator list for said block:
Steps to Reproduce
Mode: Validator
number of nodes: 1
Command:
kagome --chain kusama -d [...] --validator --listen-addr [...] --public-addr [...] --name [...] --rpc-port [...] --telemetry-url [...] --telemetry-url [...] --node-key-file [...]
Effects of the Bug
Instantly crashes, service restarts, hits same error again.
Example error log running with
--validator
:If relaunching as non-validator, get following failure:
Expected Behavior
Doesn't crash on said block. Non-validator doesn't crash but stalls on block #25830930's child (see logs below).
