Hello all,

RE: virtual server loses connectivity but processes still running

I've been taking a crack at this on and off for the last month or so,
and I believe I have discovered a possible cause.

First, I noticed this problem seemed to come up whenever a large amount
of network traffic was going to/from the virtual server, whether a file
transfer, or opening a very large file while SSH'd in.

I noticed that the setup on the three virtual servers on different host
systems were all the same:

  - COW filesystem
  - 96M RAM

so I was figuring that this could be a RAM issue, or possibly an issue
with using a COW system.

Unfortunately the latest virtual server (COW system) I setup suffered
the same symptoms, and now freezes during bootup right after enabling
swap space, so I just cimply copied over the base filesystem and used
that as my 'root_fs' to boot.  I booted it with 256M RAM, and scp'd some
rather large log filesto the system, which tended to make this proble
appear on the previous virtual servers; they went across no problem.

My next step will be to try the same thing with only 96M of RAM, then to
use a COW system with 256M RAM, and see what happens.

I will keep you posted, as this may definately be a bug or caveat that
we have here.  Or then again, it could just be me :-)
