@lambo4jos
what if you add --db.size.limit=2Tb ? (or 1Tb - depending on your current db size)

@AskAlexSharov Thank you for the response! I tested this, and also tried upgrading to erigon version 2.43.0-stable-7e8beecf and am still receiving the error seen below. My chaindata folder is 1.8TB, and the .erigon folder where all the chaindata, snapshots, nodes data, etc, in total is 2.1TB. I tried 2TB and 3TB as options for the value:

@AskAlexSharov Late follow-up to close this matter as it was a kernel config issue related to #4871. Rather than recompiling, I updated the machine to a newer arm OS version that has the newer kernel config parameter that was preventing the machine from running erigon, and the issue has since been resolved
