I tried today to upgrade my 1841 Adv Security from 12.4.6T7 using sdf v4 files to the newer v5 12.4.11T3. All went well with the initial config, three basic signatures activated. I used the v296 pkg file for the latest signatures.
When I tried to copy the pkg to the idconf, the router goes to 100 percent utilization and stays there til I reboot it. None of the additional signature engines activate, no matter how long I wait for it to compile them.
Any hints on why this is happenning? This is my first go at the new v5 format files.
