What would you figure from the above ? Hopefully the rather obvious, that it’s a *really* shitty combination.
So we figured it would be a nice thing to test our new setup before going into pre-production testing or production, but we don’t have an extra spare box. So we took one of the power4 boxes we have mounted in the rack basically consuming energy all day (that’s about 38kWh a day) and installed SLES10 onto it. Which wasn’t all that bad (at first the box repeatedly started back to AIX, from CD and after convincing the SMS – that’s basically the bios on the power*-boxes also known as System Management Services with a hammer to boot from the first hard disk).
The real bad part started later. First the box committed suicide sometime on the weekend (the last one that is), which is rather not so good.
So we installed the ocfs2-tools (which is obviously needed if you want do writes on a SAN volume mounted on two separate boxes), configured the o2cb thing to start automatically on boot and added the entry to /etc/fstab.
So far so good, but as we slowly activated the apache-vhosts, we finally came to what cost me about three damned hours of my life:
child pid ### exit signal Segmentation fault (11)
And attached also the usual crap .. “Please update to the latest version”. Only problem with that is that the latest version is indeed available for x86_64 (meaning amd64 in Gentoo terms), but ain’t for ppc (even if the product page states it should be).
So I went home, knowing what the problem is – since it was already past 4pm – swearing a short “frack that“.
Now that I’m home, ate something (a rather good salad), listening to some Korn/Kid Rock/Offspring and after doing some undertakers work, I asked myself “Why exactly do we need that crappy application anyway ?” (beyond the obvious point, that the ZendOptimizer is like/ is a php-compiler cache).
It turns out, one of my co-workers wrote a TYPO3-plugin interfacing our local research database .. and the catchy thing is, guess what …
He “guarded” it with ZendGuard, thus we need to use the ZendOptimizer thingy; otherwise we couldn’t use it either … 😯
