hello,I have some question

[Dan Huang]

Hi,
I am an beginner in ringo,I have question

action.js

var signal=""; //signal is a global obj
app.get("/getsignal",function(req){
return response.json({'result':signal});
});

and i use yui in base.html , and set setInteval to polling
the signal

there's some thing happened,I get Exception in dos cmd
like Wrapped org.eclipse.jetty.io.EofException
and I open taskmgr(win 7 home_premium),I saw
java.exe memory usage grow up by time and my system
later get Out of resource, I thought it's a gc problem,
so I change ringo.cmd
@java -Xms80M -Xmx90M -jar "%~dp0\..\run.jar" %*
but after it occur the EofException,memory still growup


How can I prvent this problem or Detect the memory
leak


//// there is the exception

Hi Dan,

Did you make any progress on this problem?  I notice nobody replied to you.  To be honest the forum has been exceptionally quiet for several months now and I don't know if there's a reason...

FWIW I've been working with Ringo for about a year or so and I hadn't noticed memory leaks like this, but we're actually not in production yet and I'd love to know if what you're seeing is real - i.e. before I get in production! :)

Did you say what version of ringo you're using btw?  I assume either 0.8 or trunk?

Also at what frequency are you "polling your signal"?  (just curious)

My week looks pretty busy but if there's a way you could zip your files up and e-mail them I'd offer to at least look them over maybe this weekend if not before.

If nothing else I could confirm that the problem reproduces on my machine.

Hi, Darren

                Thanks for your response,I learn the ringo and wrote it bcz now it's required for working.

                I use Ringo version is 0.8,about 1 second in cycle,I use setInterval(function(){},1000),

                I noticed the problem when I test, but now my computer(win 7 home premium x64,4G memory)

                I use jdk 1.7,and I change the ringo.cmd in /bin the original @java -jar "%~dp0\..\run.jar" %*

                                                                                     the modified @java -Xms80M -Xmx90M -jar "%~dp0\..\run.jar" %*

                ,still occur the exception,but the java.exe will grow up to 120m,and will release(start GC),so now it didn't eat all source

                I continue to pay close attention in this issue

  

                ps. I will ask my leader,could I package a part of code to you
