Ok, the existence of this bug just blew my mind. It appears that after coppying /proc/kcore to disk the system starts to behave strangely. Processes start to sometimes segfault randomly or die with a glibc double free error. The system is perfectly fine prior to catting /proc/kcore. I can reproduce this problem on the 2.6.18 kernel from xen 3.1.0 and 3.1.1-rc2. To trigger it I just have to run 'cat /proc/kcore >coredump' and then start hitting the system with something like a gdb compile. I usually see a segfault or some strange failure before the compile finishes. -- Michael Marineau Oregon State University mike@xxxxxxxxxxxx _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
