Android WebView randomly not responding to touch events

Hello everybody.
I have an issue with my Android Web Application.

The application is installed on a Tablet (LGV700 - 4.4.2) that runs only for that purpose (powered 24/7).

The application is a wrapper to a web application with a little extra functionality, loaded from a remote url (The webview is created dynamically in the code).

The problem is that the application randomly freezes/stops reacting to most touch events (usually after a long period of uptime) and it continuous until the application is restarted.

Checking the app with a profiler shows that memory usage is high, however the GC seems to be working fine, cleaning all the not used memory when it's about to reach the memory limit.

I tried adding largeHeap and hardwareAccelerated property to the manifest, but it doesn't seem to help.

I'm not sure it's the only problem, but sometimes the app is getting force closed, and the following error is thrown to logcat:

which looks like this problem: code.google.com/p/chromium/issues/detail?id=437017, but it seems to be fixed.

When the application detects that internet connection was lost, it reloads the webview by using the loadUrl function with original url.

Also worth mentioning is that I use "ANR-WatchDog" lib to detect Application Not Responding errors (checks if the main thread is not responding for more that 5 seconds), However it's silent when the issue occurs.

Any ideas?
