In any case, centos 4.x is way too old. I changed the kernel to 2.6.27.12-78.2.8.fc9.i686 and so far it is stable. x64 will be the next step. i686 is what our guys install by default, I didn't bother to reinstall it. -- Best Regards Vladimir Ivashchenko Chief Technology Officer PrimeTel, Cyprus - www.prime-tel.com
