Hi
When looking at some memory dumps, I see huge numbers of EOF related instances, such as, by decreasing order and with % of instance nb and % of heap size :
- _EOHandlerWeakRef 5,8% - 5,1%,
- EOAccessArrayFaultHandler 5,7% - 6,6%
- _EOCheapCopyMutableArray 2,9% - 1%
- _EOMutableKnownKeyDictionnary 2,1% - 3;3%
- _EOWeakReference 1,2% - 1%
The overall JVM is about 360Mo. Each session of the application looks like holding quite some of them (they're nicely garbage collected on session termination). So they look like editing context related.
I was wondering it there were some tricks to clean up these objects.
For example can the WeakReference be clean up somehow ? Can the editing context cache be cleaned up to retain only the dirty objects ? Or maybe to remove some of the least used entities (or not used for quite some time) ?
Any hint welcomed :)
Thanks in advance
best
