I assume you use i386 architecture. libc6-i686 was introduced for this purpose. It used floating stack, so it didn't reserve 2MB stack in glibc 2.3.2-*.deb series. However the current 2.3.2.ds1-*.deb series does not use linuxthreads on i686 optimized library. Thus, we don't support linuxthreads + floating stacks currently. > MySQL does AFAIK not (yet) use NPTL. I guess MySQL should work with NPTL - because we have not heard any problems. If you want to use NPTL, you need to upgrade your kernel to 2.6.
