thread precache panicked

See original GitHub issue

Hi,

While doing the precaching, Esplora crashes constantly with the following error and then restarts, recrashing with the same error…

I’ll check how to disable the precaching and try it…

FYI, I disabled precaching with NO_PRECACHE=1 and now our explorer is up and running.

Ok @shesek sorry for the delay. I’m back on Esplora. I will add debug verbosity and retry with NO_PRECACHE=0 like you asked me.

In the meantime, I want you to know that every time we do a search by block (hash or height), Esplora crashes. 100% reproducible. It is similar to the error above. Here is what I see the current log file:
