Memory is exhausted quickly during development [message #504229] Thu, 17 December 2009 18:35 Go to next message

Hi all,

During intensive development of RAP application in which I run
RAP JUnit mercilessly, the memory consumption is piling up quickly not
to mention the tests run slower and slower after each run. Usually after
quite sometime we have to restart Eclipse. This is counterproductive and
distractive.

Has anybody experienced the same problem ?

Any advice would be greatly appreciated.


Regards,

Setya

I have a vaguely remember that the internal browsers leaks memory
(at least IE on Windows) but I couldn't find a bug or other proof
for that.
Did you try to run the tests in the external browser?

I'm developing on Ubuntu, so the default browser is Firefox I guess. I
only try on external browser occasionally.

Before each test run I seldom shutdown OSGI from previous run first.
Could this be the cause ?

If you leave the default settings as is, a possibly running OSGi
instance will be killed before the next one is launched. But as the
OSGi instance is running in a separate VM, this would not affect the
memory consumption of your IDE.

Rudiger,

I thought the default settings is with VM argument
-Dosgi.noShutdown=true, doesn't it mean that the previous one is kept
alive ?

Also I notice that after each run, a new Java process is created using
approx. 150Mb and it stays there forever until I shutdown the OSGI instance.

Sorry, I mean it slows down the whole machine and eventually hurts Eclipse.

I was referring to "Terminate possibly running previous launch" on
the "Main" tab.

Yes, this option is always checked. So I guess its the OSGI instances
that are piling up.

If you are running the *same* launch configuration, there should be
one such instance at most.
Feel free to file a buzilla if this is not the case.
