[Jython-users] Out of memory script crash

[A B. <AB...@co...>]

Dear All,

I'd welcome some input on a memory problem I'm having with an embedded
interpreter.
The interpreter is running a script from within my app.
The script executes fine up to a point, then after a seemingly fixed number
of iterations in a loop, the javaw process rapidly consumes all of its
available memory.

For instance:



*** myScript.py ***

<..jython code..>

#script runs fine up to here
for i in range(25000):
	#the following line prints plenty of available memory 
	#but then stops after ~3500 lines
	#at which point the javaw memory rockets!
	print str(Runtime.getRuntime().freeMemory())

<..jython code..>

*******************



I have tried: 

* Changing up and down the javaw -Xms and -Xmx flags for the jvm.
* Not printing in the loop.
* Decreasing the iterations and looping over two iterators

If the loop is excluded from the script, it executes without problem!

Any help would really be appreciated,

	Ant
