Public bug reported: I usually suspend my computer (HP EliteBook 8560w) to RAM if I tranport it or I don't need it and I restart it only once a month or so. However, since a few weeks, my computer gets slow, sluggish, and ultimately freezes after using it for some hours, because some 'invisible' processes use all the RAM (8 GB). When I notice in time that there is no or little memory left in RAM so that the computer starts to use swap memory and I immediately close all programs, I can restart the computer before it gets unresponsive. I have to restart my computer at least once per day (often by pressing the on/off button for a long time, when I did not manage to restart the computer before it became unresponsive). Although a lot of memory is used, the processes that use most of the memory are not listed by "System Activity" or "top" (I will attached a screen shot and a text file that illustrate this). Hence, it seems that some 'invisible' processes use nearly all of the memory.
I ran MemTest86 (from the boot menu) but it did not find any errors. I did not use 'apport' to report this bug, because it does not really work: https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1539263 but I managed to save the information collected by apport, which I will attach. Which further information do you need? ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1540013 Title: Ubuntu gets slow and freezes, because 'invisible' processes use all memory To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1540013/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
