I've seen that error show up when java hangs, the server is frozen and won't accept any connections and this is with a unmodded server and client. Just restart the server and it will work until the next time it happens. Its not my server so all I can say is that it running on a Linux box with open java and has something to do with java running out of heap space.
Seems to be somewhat related to the items glitching through other blocks. Using a common design for a tnt cannon, a water channel with a row of dispensers on one side. I was able to make a working tnt cannon by adding a row of glass blocks above the dispensers and on top of the row across from them. Any blocks above the water channel could cause the tnt to glitch upwards. I also added an extra block at end of the water channel and let the water flow out the end of the cannon. Flight paths of the tnt are very random though.
if you want to add something in the water to hold the tnt up, use a fence and leave a one block gap to the tnt charge or one could glitch upwards on the fence and destroy the cannon.
