Better monerod OpenBSD support in future

[justanotherscript]

I dont know if it has to do with the file system or not. When I try to download the blockchain to a freebsd machine. The machine gets from monerod just a litte bit slower but still works. When I try to download the blockchain on the same hardware but on OpenBSD the system just hangs at around 40% and monerod crashes or freezes. So the thing is always the same as it seems. I tried to make the tests as accurate as possible. So I don't actually know if monerod runs only single threaded or just takes all CPU cores and RAM at once on OpenBSD. First I tried the monero package from the FreeBSD packages:

pkg install monero-cli

Worked flawlessly

Then I tried to manually compile it under FreeBSD --> worked flawlessly

Now the problem seems to exist under OpenBSD.

system info:
OpenBSD myhostnamehere 7.8 GENERIC.MP#1 amd64

Package freshly compiled with following steps:

pkg_add cmake gmake zeromq libiconv boost libunbound

git clone --recursive https://github.com/monero-project/monero

cd monero && git submodule init && git submodule update

gmake

running monerod from following location:
monero/build/OpenBSD/master/release/bin

Additions:

bitmonero.log General crashing logs:

bitmonero.log

I downloaded the whole blockchain on a ubuntu machine. After that exported it with monero-blockchain-export

After that on the OpenBSD machine tried to import it again with:
./monero-blockchain-import --input-file /home/username/blockchain/blockchain.raw

and it suddently crashed:

[justanotherscript]

@selsta additional event logs appended to the blockchain import tool. I wasn't sure if I should create for that another issue.

[selsta]

does it work if you just copy the LMDB database?

[justanotherscript]

@selsta I tried it before but instead of over 200 gb it copied only around 170 and i know for sure that it has to do with NTFS OpenBSD issues so i transfered it over the network. Someone on the official irc told me to also append loglevel 3 at first:

./monero-blockchain-import --input-file /home/user/blockchain/blockchain.raw --log-level 3
thats what iam currently doing. I would post it as comment then.

[justanotherscript]

I also added the bitmonero.log General crashing logs:

bitmonero.log

I don't know if that has anything to do with the error but I found inside bitmonero.log following at the end of the log file:
2025-12-09 05:31:34.231 7f3ef9cf86c0 ERROR randomx contrib/epee/src/mlog.cpp:517 Couldn't allocate RandomX light VM

Again it came the same error message:

@selsta Please let me know how i can send the whole log files to you. Their size is more than 25MB that's why github won't let me to upload them directly.

@justanotherscript gzip -9 bitmonero.log

@nahuhh @selsta It worked thanks

It fails to allocate memory. Could it be hitting some OpenBSD specific limit?

[hhartzer]

I've been messing with this, and Monero on OpenBSD is a mess.

Even stopping the daemon will lock up the system for minutes sometimes. You have to use certain sync options as well.

It can function, but it's tricky, and the settings to make it workable make it touchy. If the power is cut, lmdb will be corrupt and you have to start over.

[justanotherscript]

@hhartzer Could you please provide the settings to make it workable? I just want to use monero. And maybe in future create a public node.

[hhartzer]

@justanotherscript There's some mailing list discussion (ports at openbsd.org) that may be helpful, but I'll share my settings.

This is unfortunately pretty mandatory: --db-sync-mode=fast:async:10000

If you crash with this, or lose power, you'll likely have to resync the database.

I have tinkered with that setting and never had any other workable setting that is safer.

Also, if you have too many nodes, it seems to die. I think OpenBSD 7.8 crashes or hangs, but I had to limit the number of nodes either way. --in-peers=10 --out-peers=10 -- 20, or 40 may be fine. But don't expect a whole lot.

Stopping the daemon, properly, has taken up to 45 minutes for me. You may be able to do a kill -HUP, wait 30 seconds, then kill -KILL after that. But the system may not be responsive enough to second that second signal. I haven't tested this -- it may also kill the database.

It really does make the whole system unresponsive. Don't plan on running anything remotely important on the same server. That said, it does work under vmd and doesn't hang the host.

[justanotherscript]

Thanks for sharing your insights. I will test it and maybe try to make commits so that the official monero Documentation gets expanded about this thing.

dont add docs for workaround that make a crippled bug slightly less crippled. It's supoosed to work. If it doesnt work, it needs ti be fixed. None of these workaround are fixes

[justanotherscript]

@nahuhh That’s a fair point, and I agree. Documenting workarounds for broken behavior isn’t ideal — it makes more sense to wait for a proper fix and then document the correct behavior. Thanks for taking the time to clarify this.
