I got the following error when syncing my Tanganika node with the relay and parachain, i'd synced ~11846441 out of 15934569, with 11846144 finalized blocks on relay chain and 1044591 out of 1104968 blocks with 0 finalized on parachain:

i was using:
https://github.com/DataHighway-DHX/DataHighway-Parachain/releases/download/v3.7.1/datahighway-collator https://github.com/DataHighway-DHX/DataHighway-Parachain/releases/download/v3.7.1/kusama.json
https://raw.githubusercontent.com/DataHighway-DHX/DataHighway-Parachain/v3.6.0/res/kusama/kusama-parachain-raw.json

It seems related to this paritytech/substrate#12522

when i restarted the node it continued syncing relay chain blocks, but stopped syncing parachain blocks and showed the following error:

Error importing block 0x9a12c8dc3df1aab3f72ed5e0abfd7b15e9f9b50f4a15643f12058e3a5bf47897: consensus error: Import failed: Backend error: Can't canonicalize missing block number #1044592 when importing 0x9a12c8dc3df1aab3f72ed5e0abfd7b15e9f9b50f4a15643f12058e3a5bf47897 (#1048688)
