HI Rossen, I have seen the same problem from time to time. Once the load average gets above 4/5 I typically reboot, or kill the process responsible and go make a cup of tea while everything settles down again.
What browser are you running? Until recently I was having a real headache with the flash plugin in Chromium. I switched to Google Chrome and haven't suffered nearly as much since. I have seen that video calls in Skype can be the culprit as well... not much i can do about that though Cheers, Matt On 24 February 2011 06:37, <bod...@googlemail.com> wrote: > Hi Rossen, > > I have had similar problems in the past where having many tabs open in > firefox would eventually cause the whole DE to freeze up.
