ios 9.0.1 crashes frequently

I have an iPhone 6, and since I installed iOS 9.0.1, I've been having a lot of trouble with apps crashing.

The behavior it exhibits:

It's fine for a while, then it gets into a crashing "mood".
Once it's in that mood, apps frequently shut down dumping me back to the home screen. Sometimes the phone will be black and unresponsive for a couple of seconds. Sometimes the phone is black for longer, then shows the apple screen, then gets me back to the home screen. I experience this both with built-in apps (Podcast, Safari) and third-party apps.
The keyboard tends to be very sluggish while this is going on--I can type but the letters don't show up and the keyboard doesn't respond, then the letters all show up in a rush... or else the app crashes. When the keyboard is sluggish it's a good sign the app is about to crash.

Shutting down the app (by going to the app picker and swiping it up with my thumb) doesn't resolve the issue--once this behavior starts, it keeps happening, with lots of apps. However, fully shutting down the phone and restarting it does fix the problem... for a while, until it comes back.

I did a full wipe of my phone to factory settings, then restored from a backup--it didn't solve the problem. I could try doing a full factory restore and not restoring from a backup--instead, just adding in all my apps and settings by hand--but I'd rather not do that just on "spec", I'd feel stupid doing all that and having the same problem all over again.

Has anyone else experienced this? Any suggestions on what I should try? The phone was fine before I installed 9.0.1. I haven't had similar problems with my iPad Air, which also has 9.0.1 installed.

I suffered from this issue and thought for the longest time that it was the iOS9 upgrade since that's where I first experienced the problem. I've upgraded through 9.1 with the same issues ("crash moods") described in this post and have been hesitant to upgrade to anything newer since it never seemed to resolve the issue. I believe that I found the source of my issue and hopefully this will help someone out there.

In my case, the issue was caused by a rogue meeting invite for my work exchange-backed email account. Exchange (through a bug) allowed the meeting to be replicated an unlimited number of times and it killed my calendar on my desktop calendar and my phone. i resolved that issue by deleting my work email account and its local settings from my laptop and phone and for now my phone seems responsive rather than its usual "crash every 5 minutes" Mood that it used to get in on Fridays. I've been running after this for more than a week with no issues and previously every Friday the phone would crash constantly. Maybe similar situations are plaguing others and something similar can help them to resolve the issue.

I haven't upgraded to the latest iOS version yet (9.2.1 as of this writing), but since I am not seeing the crash moods anymore, I will probably upgrade in the next week. Will post back here if the issue reappears after the upgrade.
