Hi tachibana-san, I have makedumpfile filtering working now. Much thanks. Examples of filtering on a 1 GB x86_64 system, booted with "crashkernel=64M at 16M" and then crashed (sysrq-c). Various makedumpfile -d values and their results: makedumpfile -d 1 -E -i vmcore.info vmcore.002 dump002.omit.zero makedumpfile -d 17 -E -i vmcore.info vmcore.002 dump002.omit.zero.free makedumpfile -d 23 -E -i vmcore.info vmcore.002 dump002.omit.zero.free.all.cache makedumpfile -d 31 -E -i vmcore.info vmcore.002 dump002.omit.all -r-------- 1 rddunlap users 970M Sep 4 12:36 vmcore.002 // dumpfile -rw------- 1 rddunlap rddunlap 966M Sep 4 15:10 dump002.omit.zero -rw------- 1 rddunlap rddunlap 661M Sep 4 15:29 dump002.omit.zero.free -rw------- 1 rddunlap rddunlap 443M Sep 4 15:43 dump002.omit.zero.free.all.cache -rw------- 1 rddunlap rddunlap 429M Sep 4 15:55 dump002.omit.all Regards, --- ~Randy
