Zachary Dea (zdea) wrote : System slows/chugs/stutters then freezes when physical memory is low kswapd0

My laptop I have loaded with 13.10 and right off the bat I noticed that sometimes out of the blue the mouse would start skipping, the system would become unresponsive, and then completely lock up, only a power off would restore it. The next time I caught it and closed some apps right away and the system stayed alive, but following me opening more the behavior was reproduced. I started watching top while this happened and I see kswapd0 is active and my physical memory (only 2GB) is low prior to the system grinding to a halt. I'm operating an a sata3 ssd for disk and I have 2GB of swap space which was hardly used... bandwidth is lightning as you would expect so it's not like I have a slow swap space that I'm just waiting for (besides, it doesn't seem to ever wake up).

... seems to have a number of users toward the end complaining of the same symptoms and they were directed to file something here, however I didn't see any responses back indicating that it had been done, and as my system is fully up to date I have to assume this issue remains.

Thanks,

Zach
