(URGENT) Ruby crash - possible multi-threading/parallel-processing concurrency error #139
Description
About 2 of every 5 runs of a full recompile of my MN project, I get the following Ruby error showing up in my log. I'm running latest local Gems on Windows 11 x64. I'm wondering if this is a multi-threading/parallel-processing concurrency error, since it seems odd that [relaton-rfc] needs to fetch the same ZIP file multiple times...
PS. AFAICT this doesn't appear to impact the final MN output - the NormRefs and Biblio look OK (but I didn't examine every one of the ~200 refs in detail)
