After upgrading the Enterprise Gateway to version 9.8.4, the RADIUS validation services fail to start and other services fail to run (such as the

Error in the validation.log file: "text=Concrete impl library can't be loaded:"

Error in the vipdiagnostic.out file: "Exception in thread "main" java.lang.UnsatisfiedLinkError: /opt/Symantec/VIP_Enterprise_Gateway/tools/ cannot open shared object file: No such file or directory. ERROR: object '/opt/Symantec/VIP_Enterprise_Gateway/server/bin/' from LD_PRELOAD cannot be preloaded: ignored."


This issue is the result of not having the 32-bit version of the required zlib. For Enterprise Gateway 9.8.4 or later, zlib-1.2.7 32-bit is required. 

To list the installed version of zlib on Rhel:

>yum list zlib


>rpm -qa | grep zlib



Install the 32-bit version of zlib-1.2.7 on the Enterprise Gateway Linux host box.
