Trend analysis of resource leaks for Win32 machines

Hi,

Would someone please give me some pointers on a comparative trend analysis
on resource leaks for Win32 machines versus Solaris 9, LynxOS (or other UNIX
machines). Basically, I need statistics to determine how often I need to
restart these machines to avoid unplanned failures. Thanks.

You really can't compare the resource leaks and reliability of these systems
because of differences in the range of supported applications, peripherals
and systems. Having worked in the fault tolerant computer industry, even
the folks there expected that when something new came in (whether it was an
application, or a new device or system) that some level of bugs would be
found.

In the mid 90's I was part of a team proposing a fault tolerant like
architecture to most of the OS vendors. At the time I had access to most of
the vendors source (or at least parts of the source base), the overall
impression I got was that Windows NT and commercial Unixes at that point we
about comparable in quality, but that since Unix platforms were deployed and
then rarely touched they appeared more stable.

It was interesting to note that at the time all the major Unix vendors were
opposing efforts by a POSIX working group on fault tolerance. One of the
classic quotes was
"We can't put in validity checks in our OS, they could cost us 2 to 3
percent performance!" when asked about the cost of a crash on performance,
they indicated that wasn't part of managements measure of the OS group.
