Nahum, CentOS (and other Red Hat derived distributions) run a daily prelink cron job: http://en.wikipedia.org/wiki/Prelink
This (or normal system updates) almost certainly explains the changes you see in libc. A nonprivileged user will not be able to modify your libc. JDK 7 is not supported. GeoServer failures with JDK 7 are expected. If you see system corruption, you likely have a hardware problem. (This is now off-topic for this list.) Please conduct the following hardware tests: (1) Run Memtest86+ for 24 hours to test for bad RAM. This utility should be present as a syslinux boot option on all Red Hat installation media: http://en.wikipedia.org/wiki/Memtest86 (2) Run mprime/Prime95 for 24 hours http://en.wikipedia.org/wiki/Prime95#Use_for_stress_testing You can obtain mprime (64-bit Linux) here: http://mersenne.org/freesoft/ The command under Linux for stress testing is "mprime -t". If your computer can run "mprime -t" for 24 hours without errors, your computer is "prime stable". This only tests your motherboard, CPU and RAM. If you see errors, it means that your hardware is unreliable. Also install smartmontools and use smartctl to run HDD self-tests. Kind regards, Ben.
