Workplaces stopped working


Hi. I experience troubles - although no processess are being run, CPU is sometimes 100% full and I keep receiving messages that I am out of memory - but the workplaces are pretty small and not running. And nothing has changed so dramatically regarding the code since the last week, when everythng was OK. This happens event to the workplace where I did not make changes at all!
Files cannot be saved. Bundle update gets killed. Server cannot be started.
Cloud9 became useless.
Instead I get offer to buy a premium plan every few hours.
