What does the message: WARNING: abnormally high number of blocks generated, 1903 blocks received in the last 4 hours (96 expected) mean?

You will find the meaning here: main.cpp line 2100. It expects one block every 2.5 min (96 pr. 4 hours). This is part of a check function

//
// Called periodically asynchronously; alerts if it smells like
// we're being fed a bad chain (blocks being generated much
// too slowly or too quickly).
