[BUG] bitcoin-qt 0.8.1: More than 100% of CPU usage while blockchain is unsync

[DanielBTC]

Hi all,

before I started using bitcoin-qt 0.8.1-linux the CPU usage of bitcoin-qt process is reaching more than 100% of CPU usage sometimes 189% (dual core), so I kill the process and run again, and the problem persists.

Does anyone know how to fix it?
Versions 0.8.0, 0.7.x are ok.

Trying apt-get update && apt-get upgrade...

I don't have any btc. I leave the client open just to help the network.

It's better now..  but the problem is when the blockchain is unsync .
When it become 'synched' the CPU usage go to 1% again.

Same thing happened to me, and when I tried to sync it with my wallet this happened: https://bitcointalk.org/index.php?topic=155985.0

I pulled the blockchain files and the old version of bitcoin-qt from time machine and it's good now.

I wonder how am I going to upgrade if the new version will keep using my i7 cpu 99%.

I saw your topic. Good Luck.

So I think it's a bug in the new client. (?)

Thanks, I recovered everything.

It seems like it is a bug in new version, don't know how am I going to upgrade. Perhaps 0.82 version will sort this out.
