Hey Lawrence, Guess what I just noticed. The original question was on vtun 2.6, 64bit and lzo2. Vtun 26 was never built or tested on 64-bit, to my knowledge, and pre-dates lzo2 by a goodly long time too. It's probably far out of the support that's possible, and I think in the case of the original question vtun 30x should be tested.
Now, the trace/truss of your tests with 302 could tell us quite a bit, and do send them along as soon as you get them. I'll have a chance to look at it only this Monday, so don't rush to make a deadline before then. Feel free to send them along to the devel list, or just to me, if you don't want to spam the users@ list. - bish Lawrence Stewart wrote: > Hi, > >> Hey Folks, >> >> I haven't got a machine I can use to confirm this one.
