The Discord reply above was in response to someone else having a similar issue, so despite our recommendation to not run zcashd as root, let’s see if we can at least figure out what change caused this.
The most obvious candidate is that we moved from Boost 1.74 to 1.75. @jogrgo please apply this patch (patch -p1 <this.patch) and then recompile and test to see if it fixes your problem:
