What's this? "Out of ddms"?

[Robert Terry]

Does any one knows what is this repeative error message on the
console: "out of ddms"

Been getting this at random times, sometimes up to 7 times a week or 
none at all for about two weeks. Sometimes, I am forced to re-boot the
system.  Looks like if more users logged to this machine, it increase
the odds of "freezing the system". I have checked the processes and 
they looked okay to me. It happened once that it created 7 'maild'
processes in one day!! Other than that, it's driving me nuts.

Here's the legend:
