    Is there an existing issue for this?

    • I have searched the existing issues

    Current behaviour

    bitcoin-qt crashed while loading wallets at startup.

    I used to see occasional crashes on startup a few years ago, but it hasn’t been happening at all in the last couple of major releases.

    I’ve been running v26.0 for a week or two and haven’t had any problem with it crashing until today.

    Here’s a backtrace. I run it in gdb habitually because I used to see a lot of crashes and never got around to changing that when it became more stable.

    What version of Bitcoin Core are you using?

    v26.0

    Operating system and version

    Debian 12

    Machine specifications

    Linux, Intel, ssd, plenty of RAM

    It happened again.

    This node only connects to one other node. I run two nodes on the same machine. One connects to lots of peers, and this one that keeps crashing hosts my wallets, and only connects to the other node.

    Looks like the crash happens within libQt5Core.so.5, for which there are no debug symbols available.

    OK. I will install Qt5 packages with debug symbols and wait for it to crash again.

    I tried for a while to reproduce the crash but didn’t manage. Is there something special or “unusual” about your setup, for example are you loading a large number of wallets, or are some of the wallets very large?

    No, I don’t think so. I only load 3 or 4 wallets on startup. Yesterday I tried loading around 100 old wallets that hadn’t been loaded for a while. It took over 12 hours to load them all, but didn’t crash. So it’s not easy to trigger. I’ve only seen the crash twice, and both times it happened during the initial ’loading wallets’ stage of startup.

    I’ll leave the gdb session running for a few days in case there’s anything helpful I can type at it. Let me know.

    I just had this crash twice in a row.

    I was doing something specific both times. Maybe that’s relevant:

    I had been using one of my wallets on a remote machine, and had a gap of about 30,000 unused addresses in the wallet, so some utxos weren’t being shown up on the local wallet because my keypool was set to only 2500 or so.

    I shut down bitcoin-qt, thinking that I would edit keypool= in my bitcoin.conf and restart, but then I remembered there’s an RPC call to refill the keypool to any size on demand, so I restarted bitcoin-qt without editing the bitcoin.conf and immediately ran “bitcoin-cli -rpcwallet=wallet keypoolrefill 30000” and that’s when it crashed.

    I tried again, and it crashed ago. So I switched to using bitcoind instead of bitcoin-cli and it hasn’t crashed since.

    Here are the 2 backtraces. They are very similar to each other, and to the ones I’ve posted before:
