Xposed is mentioned in the log, but that's the case whenever you have it installed, even in cases where it's not the culprit. Instead, there are a couple of OutOfMemoryErrors, maybe something is taking up too much RAM.
By the way, you could use your phone without Xposed for a few days. If you get just a single of these errors again, you know that isn't related to Xposed (whereas the opposite isn't necessarily true).
Tired of updating your mod for every new ROM release?
You want give users the possibility to combine different mods without creating tons of different files for all possible combinations?
Then have a look at my Xposed framework
- modifications without APK changes!
