   Anyone who sees this, please do the following:

   • Open a terminal window with htop
   • Open another terminal window with gdb --args ./bitcoin-qt ** Type run in (gdb) ** Watch the CPU usage of the opencon thread in the htop window ** Hit CTRL+C in (gdb) when it is at 100% ** Type thread apply all bt in (gdb)

   To enable thread names in htop, select F5 for tree view and F2-“Display options”-[x] thread names to get the thread names.

   Having some problems with gdb --args ./bitcoin-qt In my case, bitcoin-qt is located /usr/local/bin/bitcoin-qt so I run gdb --args /usr/local/bin/bitcoin-qt and then run. I get what follows:

    0(gdb) run
    1Starting program: /usr/local/bin/bitcoin-qt
    2Cannot parse expression `.L1185 4@r4'.

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