So my possible solutions: Either switch to a newer glibc (which probably comes down to upgrading to slackware 13, not in the mood for that) or move the teamspeak server to a new domU. Since it couldn’t possible *cough* be kernel related, I figured the problem had to be in glibc somewhere.
To remind you guys of the problem, check out this post: Teamspeak 3.
Or summarized: starting Teamspeak 3 server beta 16 on Slackware 11 (32 bit) fails with:

2010-01-22 15:16:12.282194|WARNING |VirtualServer | 1| --------------------------------------------------------
terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::except ion_detail::error_info_injector<boost::system::sys tem_error> >'
what(): epoll: Function not implemented
Aborted

So I wondered how to figure out the problem. Digging around in libc gave some insight:

$ strings /lib/libc.so.6 |grep -i epoll
epoll_wait
epoll_ctl
epoll_create
warning: epoll_create is not implemented and will always fail
warning: epoll_ctl is not implemented and will always fail
warning: epoll_wait is not implemented and will always fail

Say what? Will always fail? That explains…. but why?!
Apparently there is another libc library that normally gets used that DOES have the proper epoll support, it is in /lib/tls . Weren’t it that the tls dir was renamed because Xen complained about it, so it doesn’t get used.

$  strings /lib/tls.disabled/libc.so.6 | grep epol
epoll_wait
epoll_ctl
epoll_create
__GI_epoll_ctl
__GI_epoll_wait
__GI_epoll_create
epoll_wait
epoll_ctl
epoll_create

No warnings. However, a quick workaround to test this conclusion with LD_PRELOAD:

/home/teamspeak/teamspeak_server-b16# LD_PRELOAD="/lib/tls.disabled/libc.so.6  /lib/tls.disabled/libpthread-2.3.6.so" setuidgid teamspeak ./ts3server_linux_x86

Ha, that’s more like it. Yeah, it fails to start because I still have the beta 12 running in another dir, but it doesn’t give the error anymore.

Googling a bit to find some details on Slackware 11 and glibc gave me a discussion somewhere on a mailinglist that mentioned that the glibc in /lib was compiled against
2.4 headers, while the /lib/tls version was compiled against 2.6 headers. That explains!
In other words, time to recompile glibc against the proper headers.
However, that task is a bit too cumbersome to post here. Long story short: it took me half the day to meddle with the glibc.Slackbuild script (and get the right kernel headers installed, etc) and I finally have a new glibc which works.

So, if you’re looking for a quick fix: use the LD_PRELOAD trick. For the more daring amongst you: upgrade your glibc — but beware that this is a DANGEROUS thing to do since it will break many things. Of course you could also upgrade to Slackware 13 and be done with it ;)

I was impressed by how far they have come. Back when I still played WoW we always used Ventrilo version 2. We never ugpraded to the new 3 version (even though thats illegal according to them….) because version 3 had a 10 slot limitation on the free server version. Of course they don’t tell you how much a license for version 3 costs, unless you want to host more than 1000 slots. Paying for Ventrilo would be fine, but paying for 1000 slots? Ha. And yeah, there are hosts that specialize in that (and make you pay through the nose for it), but we wanted to host it ourselves.

Anyway, Teamspeak 3 has a much better view of the world. They offer a -free- personal (that means non commercial!) non-profit license. This means if you’re a guild you can obtain a license
from them for free over here which allows you to host your own Teamspeak 3 server with 10 virtual servers and 512 slots. That’s more like it!
And if you ARE commercial, their licenses are well defined and very affordable. For instance a 1 year license for 25 slots is only $25. Compare that to Ventrilo 2 providers that ask you E10,- per month. Ha.
Oh, did I mention that they DO have a linux client? And windows and mac of course…. including the 64 bit versions. Lovely :)

However, as it’s still in beta I run into some problems every now and then. Today I was asked to upgade the b12 server to the latest. So I tried.
Result:

2010-01-22 15:16:11.447045|INFO    |ServerLibPriv |   | Server Version: 3.0.0-beta16 [Build: 9929]
 [ blabla ]
terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::system::system_error> >'
  what():  epoll: Function not implemented
Aborted

…. welcome back my friend…. BOOST …. always the fucking same with that piece of rubbish.
However, to be fair this could very well be a “learn to code” problem by teamspeak, but still… it’s always boost the brings the curses.
So what is it complaining now? I don’t have epoll? Seriously? Let’s see about that.

# uname -a
Linux blue 2.6.32.2-xenU #1 SMP Thu Dec 24 15:55:52 CET 2009 i686 athlon-4 i386 GNU/Linux
# zcat /proc/config.gz  | grep -i epol
CONFIG_EPOLL=y

So that’s not it.
The forum has this thread suggesting it might be glibc that’s too old.
However, this particular slackware 11 server has glibc version 2.3.6, which should be old enough (according to that forum thread at least). Just in case it’s not I’ll try upgrading that later.
In the meanwhile I created a thread on this problem on the forums, let’s see what they suggest. I’ll put updates here.
