I have noticed consistent block lag (respawning blocks), only in the Nether, while running dynmap. (Note: this has not been tested with The End.) If a player is even so much as in the nether, the console is spammed with the tick overload message "[WARNING] Can't keep up! Did the system time change, or is the server overloaded?" and the "World tick list processing calls:" portion of '/dynmap stats' increases at approx. 20 per second. This behavior stops immediately after the player leaves the nether. If "enabled: false" is set for world_nether then the issue is bypassed, albeit without a map of the nether. I have tested this, with consistent results, on both 0.26 and the current pull of 0.27 (2011-12-15T18:27).
