I did a fresh install with 7.0 on VMware, and I am not
experiencing
these problems. Could this mean that my upgrade went awry
somehow? I
have rebuilt everything pertaining to apache and php5 and it
is still
crashing. I don't know how to debug this any further. I
would like to
diagnose so that I can report a glitch in the upgrade
process if need be.
