P2Pool Node Peaking at 100% CPU for No Apparent Reason

[Ann Hashaway]

Hello,

I have got a P2Pool node on a VPS that seems to act up about every 2-6 hours. If I kill P2Pool and restart, all the miners connect back and everything works fine. CPU never goes above about 30%. Then, for no apparent reason, it will max out at least one core and the web interface of the node becomes unavailable. The only fix is to kill P2Pool and restart it. Then it repeats after a few hours.

This node has operated in the very recent past with nearly 4x the current hashrate with no issues, so I am wondering if anyone knows what is going on. After a restart, the web interface shows no hashrate during the outage, even though the CPU was maxed.

I also have another node (for a different coin) running on the same VPS, and it is unaffected.

Any ideas?

Code:

screen -d -m -S myp2pool ~/p2pool/run_p2pool.py --max-conns 50 --give-author 0.5 --net (coinname) UN PW

Make sure it has a firewall that blocks IRC because maybe it's being used as a zombie bot for a DDOS attack.
Take a look at the network traffic with a packet analyzer and see if it's spamming an IP address.
