Yes, I know of those and I meant to warn you about them... But I forgot. :<
Basically it's caused by having too many annotations in the map at once, I do have 2 simple fixes for it: 1) don't send annotations when no one can see them 2)Only process 5 annotations every second, spreading the load. Both of these are in use on one of the plugins I don't have released here, I'll itergrate them into these plugins sometime tomorrow, till then, keep it below 10 annotations per map.
EDIT: I'll try do it quickly now
EDIT 2: Applied the changes, changelog is in OP.

This isn't a job for this plugin, but could be quite easily achieved using the general structure of the plugin.
I will get around to the other changes suggested when I have some time, which will probably be sometime inbetween now and Friday.
