I have been getting this dump on my screen and I have seen it when running zmrestore and zmprov. I dont know if it is exactly the same but this is what zmrestore spits out.
It doesn't really seem to effect anything, but I have only seen it since going going from 4.5.7 to 4.5.10
Full thread dump Java HotSpot(TM) 64-Bit Server VM (1.6.0_02-b05 mixed mode):
and then some junk
I have attached one of the dumps
Anyone else seeing this or know what could be causing it?
