I've installed indicator-multiload and two days ago it showed
today it shows:
so cache memory is growing fast even though I shutdown all my applications. I am sure reboot will help but I do not want to reboot every two days.
1. What exactly cache memory is here? I assume that's when it's not enough RAM then kernel writes some code and data to swap area - am I right?
2. Is it a memory leak? Is it Ubuntu memory leak or is it indicator-multiload memory leak?
