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.

main.h

 static const unsigned int DEFAULT_MAX_ORPHAN_TRANSACTIONS = 100;
  /** Default for -maxorphanblocks, maximum number of orphan blocks kept in memory */
 -static const unsigned int DEFAULT_MAX_ORPHAN_BLOCKS = 750;

 +static const unsigned int DEFAULT_MAX_ORPHAN_BLOCKS = 7500;

  /** The maximum size of a blk?????.dat file (since 0.8) */

Increased Max orphans default to 7500.

too high. I’d try 1500.

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