- During a BIG-IP upgrade, an RPM error occurs and is logged to /var/log/liveinstall.log. The nature of the error has rpm post script failure in one of the packages. - After the rpm post script failure occurs, the upgrade status is reported as success. - Upon rebooting to the upgraded BIG-IP version, TMM logs an error that it cannot open a library: "localhost.localdomain notice ERROR: dlopen(libtcl_xnet.so) failed".


TMM fails to load a library. This can impact or disrupt traffic.
