Traffic Learning Section Stuck Loading After TMOS Upgrade to 17.1.1.2

Might be worth checking 17.1.1.3 and the more recent 17.1.1.4 release notes as well to see if that issue has already been in addressed in those versions. I know in my lab which is on the 17.1.1.3 Build 0.12.5 ENG HF does not experience that issue yet that I have seen. 

Also you could take a look at your logs (ltm, messages, tmm, asm) and recreate the issue and see if anything notable shows up. Such tomcat, restjavad and or asm processes having issue or dropping a core file. A lot of times when I run into Web Gui issues, always seems to be tomcat or restjavad having issues and typically giving them more memory helps. But just depends on what the logs show.
