I set CONFIG_SLUB_DEBUG=y CONFIG_SLUB=y CONFIG_SLUB_DEBUG_ON=y # CONFIG_SLUB_STATS is not set and tried 2.6.29, 2.6.31-rc3 and linux-mmotm from July 13, but have not been able to repro either on an i386 machine or on a KVM guest. I run your program ./tty-bug in a tight loop. I will try to run the program overnight in a loop. Given that your program does not depend on NET_NS, can you see if you can repro on 2.6.28 and see if we can bisect this problem ? | The bug causes | access to freed memory, so otherwise often nothing will happen | (the memory won't have been overwritten yet). | | OTOH, I haven't tried 2.6.31-rc3 either (but it doesn't look like fixed | there too). | | Best regards, | Grzegorz Nosek _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
