Devleopers: Are you seeing refreshes of item files being ignored after a while?

Not sure if this is something that may not be configured correctly on my system, so asking. BTW, using the 14 Jan 2017 build.

I usually get the normal:
16:59:31.320 [INFO ] [el.core.internal.ModelRepositoryImpl] - Refreshing model ‘jack.items’

16:59:31.412 [INFO ] [smarthome.event.ItemRemovedEvent ] - Item ‘Alex_Switch_Dimmer’ has been removed.

16:59:31.409 [INFO ] [smarthome.event.ItemAddedEvent ] - Item ‘Alex_Switch_Dimmer’ has been added.

types of messages in the log file, showing a rename of an item.

However, I have noticed that after a fair number of changes, I only get the refreshing line, and not the other lines showing that it processed those lines. This also seems to be accompanied by warning lines saying that a given item has already been added.

I did see this before with refreshes where there was an exception and then this behavior occurred, but this is around the 2nd or 3rd time I have seen it since installing the 14 Jan build.

Has any one else seen this?
