Ice.GC.Interval Not working as expected.

adahmaniadahmani Member Abdel DahmaniOrganization: RBCProject: RBC
Hi,

I am currently using Ice Runtime 3.2.1 and I am experiencing the following issue.

There is a cyclic dependency that has been introduced in the current Ice Objects causing a Memory leak.
Classes are written in C++.

If I make a call to Ice::collectGarbage() I can see the memory footprint going down.
This implies that the Garbage Collector is doing its work perfectly well as expected.

Ideally I don't want to be calling Ice::collectGarbage() within the code.
The document recommend using Ice.GC.Interval property.

I have set-up this property Ice.GC.Interval=5 in the Ice Property File and this seems not to cause the Garbage Collector to be run.
I have also tried to set the Property by code props->setProperty("Ice.GC.Interval", "5") without any success.

Many thanks for your assistance.

    Hi,

    Welcome to the forum.

    Note that the only setting for Ice.GC.Interval that has any effect is in the very first communicator that a program initializes. You won't need to worry about this if you're only initializing one communicator.

    Have you tried setting Ice.Trace.GC=1 to see if any log messages are generated?

    Regards,
    Mark

    Hi Mes,

    Thanks for your reply.

    I have now found the root cause of the problem, thanks for pointing me in the right direction.

    The issue is that our system contains several communicator and I was focusing on the last communicator that was created in our system.

    Once I ensure that the first communicator get initialized with the proper property Ice.GC.Interval=5 it works perfectly well.

    Many thanks for your help.
