p2pool setup errors & IPv6

[FlappySocks]

I'm trying to set up a p2pool server.  When I run p2pool (using version from git) I get this:

Code:

Error getting work from bitcoind:

I noticed, port 8332  is only available on ipv6. Is this the problem?

Code:

# netstat -lptu

Looks like your bitcoind is still downloading blocks...your P2Pool server can't connect to it until all the blocks have been downloaded.

Hang in there and it will connect.

OK, thanks, I will wait longer.  I waited until the cpu usage had died down before posting, but I just noticed, it's rocketed again.  About 30-70% on each core.

[FlappySocks]

Working now, thanks.

Good to hear!

bitcoind crashes after a while when p2pool is running. Nothing in the log to suggest why.

Should bitcoind take so much cpu when it's restarted?  If I shut bitcoind down, and then restart it again, the all 8 cpu cores go nuts for ~10 minutes.

Are you running a recent version of bitcoind? All those problems sound like issues with older versions.

I have just recompiled from git.  So far so good.

Keeps crashing.  Takes a few hours sometimes.  The log file has nothing useful in it. At the command line, it just says Killed.

$ bitcoind --debug
Killed

Ah, check dmesg. Your system is probably running out of RAM and bitcoind is being killed by the OOM killer.

Thank you. Spot on.

Code:

There is 8G of RAM on the server, but i'm running it in an LXC container. Think I limited it to 1G.  Resource hungry, isn't it.
