bitcoin/bitcoind uses almost 150mb RAM and the memory usage rises every day.
Any way to lower the usage or am i just doing something wrong? Guessing it has something to do with latest block being stored in memory or something, is there a way to prevent this?

Thanks, Daniel.

What OS are you running?

What version of bitcoin/bitcoind are you running?

Try upgrading both to the latest versions first and report back. The Bitcoin client is still in beta/testing mode, remember. We still have a long way to go before a "1.0 final" release.

Win 7 64bit & fedora 12 32bit

Memory usage seems to have went down @Win7 machine now though (to 80mb, might be because of i newly booted?), only running bitcoind on fedora and it uses as much memory as bitcoin(with GUI) on Win7. Not really sure if this is a huge problem though, maybe some other people could check their current usage and uptime on the client?

Would be nice to see lower mem usage on bitcoind but i guess it shouldn't be that high priority anyway, 140mb isn't too much and there is probaly better things to use energy on fixing for now.

Yup, for me the client(GUI) always uses 100+ megabytes of RAM....

bitcoind is running 24/7 on my debian server, and its memory usage seems to be ever increasing as time goes on:

Guess it's not only me then.

What i noticed was that it is lower when you haven't downloaded the blockchain (it starts out at about 20-30mb i believe, rising with about 1-2mb/minute (was getting the blockchain at about 600kbps i believe).

After the blockchain is completely downloaded the memory usage doesn't rise very much, maybe a 2-5 mb/h, not really sure

Since i wrote my old post it's risen from 80 to 98mb though. (7 hours)

Yeah, there is definitely some kind of memory leak, although it's very small. But a lot of people run the client 24/7, so it builds up.

So is there anything (besides digging in the source) to limit this on linux?

There were a few changes about a month ago (that will be in 0.8.2) that hugely decrease memory consumption with a lot of connections.  You might try building git master (obviously not supported and dont do it with a lot of coins/as a merchant/miner/etc) and running that, or just wait.

running 0.8.1 bitcoind on x64 linux, the mem climbs to 1.5g within 20 minutes. I'm restarting it 2-3 times a day. Once it gets so big like 2.2G, it's really difficult to shutdown the deamon gracefully. Are there some parameters that I should try to mitigate the problem ?

(tried the 0.8.2 a couple days ago noticing that the mem usage was still significant like gig+, and it halted on getaddress command, guess it's a bug or something, so I switched back.)


Note that I used the bootstrap.dat from torrent to get started and having more than 20 connections.

Do you have a massive wallet/huge number of transactions?  My node has 47 connections (I sometimes get up to a few hundred) and memory usage on 0.8.2 doesnt go above 500m.

It's been stable between 600m-1g for a while now after it caught up with the blockchain. I guess it has a tendency to use a lot of memory downloading block after being outdated.

bitcoind 0.8.1 had a memory leak in it. But 0.8.3 can run comfortably on a 512MB RAM VPS

This is what I am seeing on my VPS:

bit@hghg:~$ free -m
             total       used       free     shared    buffers     cached
Mem:           768        488        279          0          0        115
-/+ buffers/cache:        373        394
Swap:          256         34        221

So yeah 300-400MB of RAM.

so this could be a potential reason why U get the bluescreen and physical memory dump from timeto time?

Maybe I should switch to electrum...

Well my bitcoind installation crashed after a week of uptime. Maybe it was killed because it ran out of memory. I thought this problem was fixed in the 0.8.3 version.

bitcoind runs without memory leak, but memory usage is high (1.2 GB on my setup, uptime 100 days now).
