[rules-users] Web Service deploy out of memory

[Michael Neale]

Hi Edgardo.

Well it shouldn't leak like that.

Looking at your code, I am not sure how it works (as I am not sure of the
Web Service component you are using).

But if the web service is creating a new instance of the ValidaLlamadaWS
class for EACH call, then yes that woudl be the problem. What you want to do
is have the code for the agend called only once, on startup, and then use
that single instance of the agent to get a rulebase for each call.
