There are lots of problems with all UNIX's/OS's especially Linux. When one says Linux is rock-solid, what version? Is this running on a muli-CPU machine stressing the new SMP code? Are the applications multi-threaded stressing the new kernel threads added to Linux?

When one says Solaris, most assume Solaris 2.5 or 2.5.1 with no patches. When one says Linux, the Linux people useally mean the latest and most stable patched version.

It's an Apple and Oranges comarision.

My Linux friend is always upgrading to the latest RedHat Linux version because each version is better than the last.

I've run NT that crashed like crazy, adding a service pack took care of the problems. But at the time NT 3.51 you could say was easy to crash on the Compaq system we were running until you got the service pack. And what was crashing the system was the fact we had ported a multi-threaded project developed on Solaris to NT, and and it was the threading (kernel threads) that was causing the kernel to crash. With out the threaded apps running all was fine. Once patched we were good to go. That was my last experience with NT, a fun project as I now know the enemy :) but I'll stick with UNIX.

Some would be happy just to have a car. :) Received on Tue Jul 22 1997 - 00:00:00 CDT
