What's your hardware? Are you running multiple processors? Do you compile your own Apache2 and mod_jk/mod_jk2?
Have you tried compiling your own kernel from the more recent sources. Kernel 2.4 had some shaky releases and RedHat8 fell in the middle of it. Kernel 2.4.22 is the latest. Have you tried setting the environment variable: LD_KERNEL_ASSUME=2.2.5?
