I have a box running CentOS 5.x 32 bit. I noticed these kernels are installed. [root at ns1 log]# rpm -qa |grep kern |sort kernel-2.6.18-194.11.1.el5 kernel-2.6.18-194.3.1.el5 kernel-2.6.18-194.8.1.el5 kernel-PAE-devel-2.6.18-194.11.1.el5 kernel-PAE-devel-2.6.18-194.3.1.el5 kernel-PAE-devel-2.6.18-194.8.1.el5 [root at ns1 log]# uname -a Linux ns1.xx.net 2.6.18-194.11.1.el5 #1 SMP Tue Aug 10 19:09:06 EDT 2010 i686 i686 i386 GNU/Linux [root at ns1 log]# free total used free shared buffers cached Mem: 1025500 687176 338324 0 87824 535628 -/+ buffers/cache: 63724 961776 Swap: 2031608 0 2031608 This machine only has 1G of RAM. Should I just remove the PAE kernels? Matt
