This is a known problem and there is a patch for that:<br>
<br>
<a href="http://bugs.centos.org/view.php?id=3156" target="_blank">http://bugs.centos.org/view.php?id=3156</a><br>
<br>
Your kernel is so old (meaning many security holes). Please update the<br>
system and while doing so, grab the centosplus kernel which has the<br>
fix for this issue.<br>

</blockquote></div><br><br clear="all"><div>Hi <br></div><div>Thanks for you reply , currently we have the default kernel 2.6.18-128.el5 ( centos 5.3 ) , can i install the kernel-2.6.18-8.1.8.el5.src.rpm and add the patch to this or do i have to download the kernel 2.6.21 then compile it and then install it . I had been to the <a href="http://kernel.org">kernel.org</a> and cant find the kernel 2.6.21 , the kernels available are 2.6.27.49 and above . </div>
