Thanks for your help!

Hi Peter,
This seems to be a bug. Please open a bug report with the info
you've already provided, and I will fix in time for our next
minor release (3.13.6). I've already pretty much written the
fix, so this can all go quick.
Thanks,
Scott

I now removed our custom code - I don't think it has
something to do with this issue.
current state:
on every client connect one ore more (depending on the number
of published services) "ID targetContainerID" Objects are
added to a List in the Map localRegistryUnregistrationTargets
in the RegistrySharedObject on the Server Side.
the call stack is:
Daemon Thread

I don't see any code that removed entries from the List in
Map when the Client disconnects. So the List (and with it the
Map localRegistryUnregistrationTargets) grows until there is
no memory left.
Any help on this topic would greatly be appreciated.
thx Peter

Hi all,
sorry for double posting - hotkeys are evil sometimes...
for custom error handling on server side (please see previous
discussion on this list as of 27.06.2014 with the subject
"Exception Handling of Remote Calls") we use a derived
HostContainerSelector and a derived RegistrySharedObject. See
code below.
The problem seems to be that we create a instance of
RegistrySharedObject (P4RegistrySharedObject()) wich gets
added to
org.eclipse.ecf.provider.remoteservice.generic.RegistrySharedObject.localRegistryUnregistrationTargets
but "no one" calls
org.eclipse.ecf.provider.remoteservice.generic.RegistrySharedObject.sendUnregister(RemoteServiceRegistrationImpl)
when the remote client disconnects.
So the Map grows over time and finally the server run's into
an OutOfMemory Exception after some time.
Any suggestions where the Problem is or what is missing from
the implementation?
thanks in advance!
Best Regards, Peter
BTW: we are running ECF 3.13.1.v20160405-1820
extended HostContainerSelector:
@Override
protected IRemoteServiceContainer createRSContainer(
@SuppressWarnings("rawtypes") final
ServiceReference serviceReference, final Map<String,
Object> properties,
final ContainerTypeDescription
containerTypeDescription) throws SelectContainerException {
final ISharedObjectContainer container =
(ISharedObjectContainer) createContainer(serviceReference,
properties,
containerTypeDescription);
final ID adapterID =
IDFactory.getDefault().createStringID(IRemoteServiceContainerAdapter.class.getName());
final ISharedObjectManager manager =
container.getSharedObjectManager();
ISharedObject so = manager.getSharedObject(adapterID);
if (so == null) {
so = new P4RegistrySharedObject();
try {
manager.addSharedObject(adapterID, so, null);
} catch (final SharedObjectAddException e) {
throw new P4ServerException(e);
}
}
return new RemoteServiceContainer(container,
(IRemoteServiceContainerAdapter) so);
}
P4RegistrySharedObject extends RegistrySharedObject and just
implements a custom getSerializableException method - since
the original one is private, it's a copy of the
executeRequest method.
