Hi, all our production servers are running Centos 6.9. When I follow the APM php agent installation guide here (www.site24x7.com/help/apm/php-agent/install-php-agent.html). It always fails due to 

GLIBC version too low.

[root@server6 bin]# sudo sh configure.sh us_f4e336487890xxxxxxxxxxxxxxxxxxx

./installer: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by ./installer)

Error while installing phpagent

I believe all Centos 6 OS only comes with GLIBC 2.12. Is there any way I can install the php agent in Centos 6 system? Some suggest we can force GLIBC 1.4 to be installed in the Centos 6.x, but more others against the idea, as it may introduce long term instability issue to the production system. Please advice.

Thanks.
