Hi,
The critical bit is that Context.finalize() is being called:
>>org.dspace.storage.rdbms.DatabaseManager.freeConnection(DatabaseManager.java:733)
>> at org.dspace.core.Context.abort(Context.java:260)
>> at org.dspace.core.Context.finalize(Context.java:384)
This is effectively the Destructor for the context object, which is
called when the garbage collector picks up a discarded Context object.
I get these periodically too, and they appear to be the result of some
sort of connection leak, although I've not been able to track it down.
Presumably a Context is initialised and a database connection opened,
but that connection is aborted without the context object itself being
completed (I think). Then when the Context is discarded, a second
attempt to abort causes the below error.
If anyone else has any further experience on this, or ideas how we might
isolate the problem that would be great!
Cheers,
Richard
