About 2 days ago all the Google applications on my phone started being very unreliable. The one I use most, Gmail, is constantly restarting. Usually the first time I try to open a message the whole app restarts and then I can open the message, but often it will restart again before I get through the whole thing. There is no error message of any kind, it just restarts. I've had similar, but less frequent, issues with Google Talk and Google Voice that started at the same time. I originally thought it was just that I was out of memory, but I tried killing everything with TaskKiller and it didn't fix anything. I think the only change I've made to my phone recently is installing Skype and I kind of need it at the moment. Has anyone else had these issues or know how I could fix them?
