        2017-08-12 10:33:13 StealthSecret failed.rv=5

        wallet.cpp - Line 2060

              {
                    if (fDebug)
                        LogPrintf("StealthSecret failed.rv=%d \n",rv);
                    continue;
                };
        

        Add fDebug test to message, stealth fails due to not being included yet. Message must by misinterpreting some (orphan) blocks as having stealth addresses?

                                I’d keep the last one, as ACP checkpoint checksignature failed is relative important

                                  I’ve been through and added more, if (fDebug) (as opposed to just commenting them out) .

                                  Most of the debug messages are still there, you just have to run -debug to see them. The checkpoint “error” did not seem to be a “Fault”, just a none complaint checkpoint.

                                    [FAQ] What is the difference between LogPrint() and LogPrintf() in the Feathercoin/Bitcoin source code?

                                    Under normal conditions the LogPrintf() should only be used to report an unusual error, otherwise it is used during development to confirm an action and commented out for production versions.

                                    Writing unnecessary messages to debug slows the system and takes up disk space. Whilst the debug can be shrunk, this relies on additional parameters being passed or set up at install time.

                                    LogPrintf() statements log the output into debug.log file. LogPrint() statements only out put to the log file if -debug is set.

                                        too high. I’d try 1500.

                                        There is a reason to limit the max number of orphan blocks

                                          I’ve tested it at 10,000 and that is (7500) what Dogecoin raised it to. There is no point it being lower, it was set too low.

                                            @wrapper it’s a security measure against (D)DOS attacks to the BC, so it will work even when set to 10000000, but may stall the BC, if someone injects a high number of orphans. I’m not sure how many orphans an attacker could create, but…
