Sorry, I don't think that information really tells us anything new. Lots of memory used for the page cache, which isn't surprising. slabinfo does show a large increase in the size of the buffer_head slab at the end, which indicates a lot of stuff waiting to undergo I/O, and again not surprising.
Well, it was worth a try. I've seen systems that ground to a halt because of an in-kernel memory leak or similar creating enormous system- wide memory pressure. But that doesn't seem to be what's happening here unless something went horribly wrong after the logs stop. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/755066 Title: heavy i/o on sandybridge systems with small memory footprints causes system hangs -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
