3. Error with consensus: unexpected fault address

Error with consensus: unexpected fault address

  • M

    I am getting the following error when starting the siad daemon (v0.6.0) on Debian.
    From what I can tell it cannot fully load the blockchain, therefore I cannot use the wallet, host etc.

    Below are the first messages I get when executing ./siad -M gc

    Loading...
    (1/2) Loading gateway...
    (2/2) Loading consensus...
    Finished loading in 0.442046251 seconds
    unexpected fault address 0x77697040
    fatal error: fault
    [signal 0xb code=0x1 addr=0x77697040 pc=0x82f8bf6]

    After that, I get a lot of goroutine messages until it exits the program.

    Would be extremely helpful if you could provide the first goroutine. I think it's the same problem as described here: https://github.com/NebulousLabs/Sia/issues/1237

    The more examples we have of the failure, the easier it will be for us to get to the bottom of the crashes.

    Thanks a bunch. We'll be looking into it soon, try to have a fix ready so it stops crashing people's computers.
