Is the 64 bit VM production ready?

Hi,

Is the 64 bit VM considered anywhere near production ready? Running an
image prepared with the ImageWriter under Ubuntu 64 and loading
packages from store does sporadically result in a crash.

Hi Wouter,

We have been using 7.5 on Ubuntu 64-bit and haven't noticed any serious
problems, during runtime at least.  I got my first crash loading
something out of store today, but I've been using it for a while now and
haven't experienced this as of yet.  Strange.  I've also noticed some
performance problems in loading packages with a lot of shared variables,
or defining shared variables..  I wonder if it might somehow be related
to the crashes when loading from store, or if it's totally unrelated.

I would be interested in hearing other people's experiences with the
64-bit VM.

Yea, I'm still waiting for win version to see where the shared perm space benefit breaking point for us would be. Here's to hoping it comes out sooner than later...

Umm, no, I do not. Where did all the talk about it come from then? Hype machine at work? In all my mentions to various people at sts you're the first to point out an obvious hole :)

you know that shared perm support is not yet implemented for any platform don't you?

In my limited experience, no. As I reported week before last about 7.5
on Linux:

   I had trouble keeping it running -- the VM would exit on parcel loads,
   use of Store, etc.  These were not repeatable, but I don't think I
   ever kept the thing running for more than five minutes at a time.

I'm running on a modern Linux box. 32-bit VW is quite stable in this
environment. But in 64-bit, some times the VM would just exit, other
times I'd get a walkback saying something like "about to execute invalid
bytecode", and the VM would exit a couple of seconds later.

If someone has suggestions on how to get debugging information, I could
try to get some.
