I was getting them initially. Tried a factory reset and restored all of my apps with only minimal data and still got them.
Then did a factory reset again, started restoring apps one at a time only as needed from Google Play, no Tibu. I did this slowly, installing two or three at a time and then using the system for an hour or more to verify non-flakiness. Did not install an alternate launcher (had been using Apex). Avoided freemium games that do push notifications. No major problems since.
Did find at least one app that may be problematic: Google Voice seems unstable for me. There were couple of others too, IIRC, but that's the one that sticks out in my head because I use it fairly regularly. Did not reinstall a lot of stuff that I never actually used.
The process was painful but highly recommended. As the system becomes heavily loaded it tends have a lot of junk that is running all the time and taking up memory, etc, which is a real issue for ASUS' ICS firmware. This is why games are flaky on the TF and is probably the source of a lot of the seemingly random weirdness that seems to only affect some people but not others, IMHO, because it makes the system too sensitive to what you have installed/running on your box which is different for everyone.
This why a factory reset seems to magically fix everything, too, because all of that cruft gets wiped until you start reinstalling all this junk and firing off all the associated processes (which in turn start background services/process, etc).
I will still occasionally run FMR memory cleaner when the machine is acting laggy or something crashes (usually gmail, lol) and everything clears right up. My two previous TF201s and my other TF700 were ALL like this. I'm convinced it's an ASUS firmware/kernel issue. I'm hopeful JB fixes it but have learned to pay attention to what I put on the thing in the mean time and it is running better than ever.
rooted, btw.
