What does GLIBC_2.4' not found mean when Geneos web server starts up?

RHEL 4 is not supported by Geneos. ITRS support the following Linux versions:

Geneos version GA3.1.X and newer

Linux Redhat: RHEL 5.x [kernel 2.6.18] 
Linux Redhat: RHEL 6.x [kernel 2.6.32] 
Linux Redhat: RHEL 7.x [kernel 3.10.0]
Linux Suse: SLES 10.4, 11.x, 12.x 

Next is the OS' GLIBC library (i.e. libc-2.3.4.so). The library is lower than GLIBC 2.4. GLIBC 2.4 is required to run the Geneos Web Server.

Given the above findings, the next step is to install and run the Geneos Web Server on a supported OS version. The OS also should have the GLIBC 2.4 library installed.
