yeah, thats the problem with PyAIML (it eats too many resources for XO-1, on not havy loaded XO it should be ok), maybe we need to reduce alisochka.brn (which is reduced db of alice) much more..

[tonyforster]

Maybe some sort of recovery strategy under memory stress. Audio warning that it is under memory stress, do not load the AI and keep the text to speech still functional?

Replying to tonyforster:

At least we can't do that on activity side, doing that somewhere out of activity is a different story..

I was too optimistic for "on not havy loaded XO" :), at the end I've reduced AIML db by one third and add free memory check to not load db if there is not too much memory. These changes comes with newly released v19.
