Hi there, I run Bitcoin-qt 0.8.1 on Ubuntu 64bit with 1.5GB memory. A few hours after starting and synchronizing with network, my system start to respond very slow (running Chrome and Firefox). Looking at task manager, I see that Bitcoin-qt consumes great part of memory and almost infinite amount of allocated virtual memory, see picture below.
Just after starting and synchronizing bitcoin-qt, memory usage seems to be more normal, see picture below.
I think this high VM usage and slow system response has caused bitcoin-qt to crash occasionally (without warning or notice). The jump in VM usage seems to happen when reaching ~40 active connections. I tried earlier versions bitcoin-qt 0.8.0 and 0.7.1 and they have same issue. Would it help if I limit the number of connections in bitcoin.conf?
Bitcoin-qt on Ubuntu 64 takes 16777216 TB virtual memory, slows system #2485

Ok this worked for me, limit number of connections to 30 keeps memory use below 400MB and VM at 1.9GB. Done this by setting [maxconnections=30] in bitcoin.conf

git head (to be 0.8.2) has some memory usage reductions and other related improvements. Nothing specifically reducing virtual memory, but could you retry with current code?

Confirm. Gentoo x86_64, bitcoind 0.8.1, huge memory using. 1 Gb!
Added: sipa, I tried and post a new issue.

I lowered to maxconnection=25 and on average mem usage approx. 400MB, not crashed so far but one time saw VM usage still at 16..TB limit. Sorry I'm not that technical, how can I test with current code (git head 0.8.2)? Do I need to compile something for that? Don't know if I'm able.

It's easy. Open Synaptic package manager, open Repository properties, select "Source", Apply, update repositories.
Open Terminal.
mkdir bitcoind-source cd bitcoind-source sudo apt-get build-dep bitcoind git clone https://github.com/bitcoin/bitcoin.git cd bit[TAB] cd src make -f makefile.unix bitcoind ./bitcoind
Open other terminal and change working directory:
cd ~/bitcoind-source/bit[TAB]/src ./bitcoind getinfo

Thanks for the instructions, now running version 80199, connections=84, memory usage <400MB, VM usage 1.2GB and running great (so far), see picture below:
Would it make a difference if I run the GUI?

Closing this; bitcoind still requires a lot of memory, but some database parameters were tweaked it shouldn't be this bad anymore
