   Umbrella issue for 26.0 testing. Please help testing on a wide variety of supported platforms, as well as interaction with different software.

   Let us know which version you tested on which operating system.

   If you find an issue, please search Github for known issues first and then open a new Github issue.

   This meta issue should not be used to report bugs, as a single thread makes it impossible to track more than one topic.

   See 26.0 Draft Release Notes for a list of changes.

   See here for the testing guide: https://github.com/bitcoin-core/bitcoin-devwiki/wiki/26.0-Release-Candidate-Testing-Guide.

   The link to the release notes draft doesn’t work for me.

   Running two 26rc2 nodes, using binaries from bitcoincore.org, one on aarch64, one on amd64. Both are also on Tor and v2transport-enabled, connected via v2 at least to one another node running daily master.

   Apart from local bitcoin-cli connections keeping bitcoind from restarting, which is present for some time since around v25 on master, everything works fine. Thanks.

   Testing v26.0rc2 on an armv7l device with 2 GB of RAM.

   It fails to catch up with OOM when the cache size reaches appr. 125 MiB.

   There is no such an issue when running v25.1.

   The bitcoin.conf file contains:

   0dbcache=100     # default=450
   1par=4           # default=0; nproc returns 8
   2disablewallet=1
   3mempoolfullrbf=1
   

   All binaries are downloaded from https://bitcoincore.org/bin/.

   Could #28440 be related?

   Does it also happen if you compile from source? If yes, you could try bisecting (without having to go through guix builds)

    So, I got an OOM on a Raspberry Pi as well, syncing 26.0rc2 from genesis. My Pi actually has 8 GB RAM. I have been running 25.0 on this same device ever since its release but I did not have to sync from genesis because I was just upgrading.

    It does.

    If yes, you could try bisecting (without having to go through guix builds)

    Due to unknown to me reasons, the natively compiled binaries, at least bitcoind -reindex-chainstate, are significantly slower than Guix built ones. Therefore, I’m in the middle of bisecting using Guix builds.

    The log [...] cache=232.0MiB(31044257txo) indicates that here too something might be wrong with the DynamicMemory calculation. when having 31 million txo in memory cache size should be much higher.

    Testing v26.0rc3 on an i7 12gen with 32 GB of RAM compiled from source on Ubuntu 22.04.3 LTS.

    So far so good. I’ve also followed the 26.0 Release Candidate Testing Guide entirely, and I’d suggest others consider doing the same.
