Your server is using PHP4 which is past end-of-life. Upgrade to PHP5.
HMmmm, maybe you know something I don't? My server stats sir...
Apache version 2.2.14 (Unix)
PHP version 5.2.11MySQL version 5.0.81-community-log
Architecture x86_64
Operating system Linux
Kernel version 2.6.28-10.7.intel.E1000E.BHsmp
As such, instead of guessing and now armed with better intel, possibly you have a solution instead of a guess.
