    I am experiencing a boost in CPU usage once I used a the Bitcoin daemon over Tor&clearnet with a hidden service. The CPU usage was very low when my Bitcoin node was only on clearnet but rigth now is always using one or two core at 100%, out of 8 cores nearly all the time.

    I was expecting a similar or at least slightly higher CPU usage over Tor compared to a clearnet node.

    imagen

    The issue is continuous. I have usually 12 outbound connections (over Tor or Clearnet) and 3-5 inbound connections over Tor.

    My bitcoin version is the v0.18.0

    My sistem is an Odroid HC1 with an SSD. The OS is Ubuntu 16.04.6 LTS XENIAL. I am using a lightning node over LND within the same system.

    I don’t see anything strange other than a lot of refused connections on debug.log. I attach the last lines of the debug.log file.

    If you enable to show threads in htop, what is the name of the thread that uses all the cpu?
  3. perefeliu commented at 11:34 am on May 10, 2019: none

    I’ve anbled “Show Custom Thread Names” and if not mistaken, bitcoin-opencon and bitcoin-addcon are the threads consuming CPU. Nearly all the time, it is bitcoin-addcon. Usually both.

    Might be the same as #15665.
  5. MarcoFalke commented at 11:39 am on May 10, 2019: member
    This one also shows a spike in addcon

    addcon is running nearly all the time, rather than a spike, it is more of a constant charge on CPU. opencon follows more an spike pattern. I’m trying #15665 but having some problems that I have written within #15665. I will come back with results.

    I am having trouble following #15665

    This is what I get:

     0(gdb) run
 1Starting program: /usr/local/bin/bitcoin-qt
 2Cannot parse expression `.L1185 4@r4'.
 3warning: Probes-based dynamic linker interface failed.

 9Could not connect to any X display.
10[Inferior 1 (process 3987) exited with code 01]

    Do I need a display to perform that action? I also assume that I need a the bitcoin daemon to be running.

    I also checked the flag debug=net and I don’t see anything outside normal. Could it be a DoS by some of the nodes?

    If you are not using the gui, but bitcoind, replace bitcoin-qt with bitcoind in those instructions, please

    Can confirm similar symptoms (1 of 4 cores running at 100% almost continually) in v0.18.0 when using a SOCKS5 proxy with Tor running locally. Network settings as per screenshot. This is on Ubuntu 18.04. I did not experience this issue in v0.17.1 with the same settings. Only workaround appears to be to stop using the proxy.

    Doing what is asked in #15665 does not appear to solve the issue, if I’ve done it correctly.

    To be clear about what I’ve done, I’ve stopped the bitcoind as a service. After thatm I run gdb and wait until I see the bitcoin-addcon thread start, (which is instantly, no need to wait). To perform this action, I’ve stopped the LND service, so it does not appear that LND is causing the issue.

    If you use only “connect” and disable “listen”, the problem goes away.

    So, it does seem more like some DoS bug exploit.

  17. perefeliu commented at 1:47 pm on June 1, 2019: none

    Interesting… @initCCG thank you for the hint. It hasn’t been fixed in my case with only disabling “listen”. To be more specific, I’ve changed the line from listenonion=1 to listenonion=0. The onion service is no longer created, but the addcon thread still at 100%.

    Then I’ve then masked all lines that connected me to other Tor nodes such as addnode=kvd44sw7skb5folw.onion . I took the list from here

    Right now the problem is solved, so perhaps there’s indeed some node in the list that is DoS-ing. Would it be useful to identify this/these nodes?

  18. jb55 commented at 5:15 am on June 4, 2019: member

    Seems like it’s spending most of it’s time in:

    0static IntrRecvError InterruptibleRecv(uint8_t* data, size_t len, int timeout, const SOCKET& hSocket)
1{
2    int64_t curTime = GetTimeMillis();
3    int64_t endTime = curTime + timeout;
4    // Maximum time to wait in one select call. It will take up until this time (in millis)
5    // to break off in case of an interruption.
6    const int64_t maxWait = 1000;
7    while (len > 0 && curTime < endTime) {
8>        ssize_t ret = recv(hSocket, (char*)data, len, 0); // Optimistically try the recv first

    @MarcoFalke I think so. However I’m going to close that issue, and re-milestone this one, as this has a bit more discussion.
