QTKitserver Safari Web content not responding-Mavericks

I have got a slew of "QTKitserver Safari Web content not responding" errors, since I updated to Mavericks. I noticed these in the new activity monitor. So it is possible that, these errors happened before without I noticed them. Either way, I'd like to ask if somebody is aware of the same issue and the possible resolutions to it. Thank you in advance.🙁

QTKitServer Not Responding

I have the same issue that started with Mavericks. Hopefully someone will come up with a solution.😕
 
Brand new Macbook Pro Retina 15", installed Adobe Flash, Creative Cloud and I'm seeing this now (though it might have been there out of the box). AppleCare had me do the following:

* Remove the com.apple.safari.plist file from your user folder
/Users/[your username]/Library/Preferences/com.apple.safari.plist

* Erase all files in the system and user cache at
/Users/[your username]/Library/Cache
/Library/Cache

Reboot.

So far so good...
 
I have this happen, but not just in Safari. It happens in Pocket too. Strangely it doesn't actually affect the applications.

I did this and everything is running fine. I couldn't find a library in my user file, but after I emptied all my library caches, I didn't get so many unresponsive processes.

Did this end up still working for you? I did it myself today. I'm at the end of my rope with these QTKitServer not responding processes in Activity Monitor on Mavericks. They show up occasionally, so I did what you just said. Did that really work for you? I know you posted that awhile back, but I was wondering if it fixed the problem? I'm crossing my fingers. 😕

I tried the method mentioned above except deleting safari preference file, because I don't want to lose the saved settings. But it didn't work for me.
 
I think this is a bug. Either in Safari, in QTKitServer or OS X Process management. None of the above suggestions made a difference for me.
I suspect these are the orphans left over when one closes tabs, but they aren't terminated until Safari closes.
Actually, I haven't tried to track them meticulously. Might be that OS X still kills them based on memory needs.
As far as I can see from the sampling of the process, they all die on sending a mach message:

It sure seems to have fixed it for me. The only other problem I was having was soagent was becoming unresponsive for me. There's some weird thing I did with flash player that fixed that.

Some apps show up like that on Mavericks. They seem to work normally, just appear not. Anyway it's weird to see it happen to a built-in app. Hope they fix it soon.
 
I have that happen all the time.

A developer told me when I reported it that it had to do with content that is requesting deprecated codecs in QT in 32 bit mode or something...can't quite recall. Apple's going in a new direction. Said it wasn't anything to fret over. I've gotten as many as 7-8 instances of this and it hasn't had any detrimental effect on my system other than using a minute amout of resources.
 
I still have it, I enjoy being able to open stuff with Quicktime and it still hasn't given me any problem about being unable to playback files..
Anyway, it looks like it's not its problem, so meh.
