Without some more info on the memory issue, I'll assume there's no security problem.
As for the IO errors, please attach full dmesg output, and describe exactly what steps you take to reproduce the problem. ** This bug is no longer flagged as a security issue -- Kernal 2.6.15-26 Server Memory Leaks and Disk I/O errors https://launchpad.net/bugs/55692 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
