Hello Dave, While I am using 'kmem -p', I feel it is too slow, especially with a big memory. So I modify something to improve the performance. The patch is based on crash 6.0.2, and it has been tested on RHEL6.2_x86_64, RHEL6.2_i386, RHEL5.8_x86_64 and RHEL5.8_i386. Thanks, Qiao Nuohan -- Crash-utility mailing list Crash-utility(a)redhat.com https://www.redhat.com/mailman/listinfo/crash-utility

When you directly call malloc()/free(), and then any kind of fatal error occurs, or if you enter CTRL-C before the command completes, then the 1MB buffer would get leaked. Any buffer allocated with GETBUF() is guaranteed to be freed by restore_sanity() prior to the next command prompt. (FREEBUF() is never necessary, just good practice.) I'll test this on a set of different kernels tonight. Thanks, Dave
