Close your collection! You probably have custom code that is not closing a collection properly. Best practice is to perform IDfCollection.close in a finally block to ensure that it's always closed properly.

Hi please see below for more detail,

Resource Housekeeper Error CollectionHandle$DisposableData:- [DFC_QUERY_NOT_CLOSED] Unclosed Collection found during gc, com.documentum.fc.client.impl.collection.TypeDataCollection

com.documentum.fc.impl.util.ThrowableStack: Stack when collection was obtained at

com.documentum.fc.client.impl.collection.TypeDataCollection.newInstance(TypeDataCollection.java:31)

And I don't use IDfcollection in my code, just use IDfSession to get session and IDfSysObject to store some stuff.

I turn on the dfc.diagnostics.resources.enable=true, this error message appears, not sure if it cause this error.

I'd appreciate any help!!!!

Is this the same issue as this:

Unclosed stream found during garbage collection in DFC — OpenText - Forums

If so, then look at the details in the other thread.

I have the same problems .Have you solved this?

I think I did not use any IDfCollection .And release the sessions in a finally block. But the error keeps showing
