[solved] 4gb fixup problem end

WARNING: try at your own risk.
2. not use this function when memory below 512MB
3. this break down my production server http://blog.apis17.info/2011/09/segmentation-fault-after-glibci386.html -reformat and reinstall solve the problem

finally 4gb fixup on xen is finally gone. (now i have openvz too :) 2.6.18-274.el5.028stab093.2xen

it fixed using i386 version of glibc

#yumdownloader glibc.i386

then yum downloading 'glibc-2.5-65.i386.rpm' package

#rpm -Uvh --force glibc-2.5-65.i386.rpm

it force 32bit glibc version. default my centos  use i686 even os 32-bit. you can read my previous entries. (thanks to cloudlinux forum)

after several hours recovering back from my lost glibc uninstall thanks to webmin saving my life.
and NEVER use this command rpm -e glibc


now i'm ready to get dangerous on production server. will update this post later.
