arbitrum: missing trie node when using parallel snapshot-downloader

[cjorge-graphops]

at least when using snapshot downloads, encountering this error:

feedOneMsg failed to send message to execEngine err="commit aborted due to earlier error: missing trie node 64cbf2db5d082820d7915d9be96ead97aed09c2f8d28ca63e387d107511087f3 (owner ed90744e9f14b1ed4141f18a59962c8af936df0fab19db4889befa008633850a) (path 0e0d) <nil>" pos=86440022

Needs to be investigated if it's caused by inadequate snapshots upstream, or something else.
