i did so, but it revealed not much (any?) more information:
Feb 25 03:05:17 sheep kernel: __alloc_pages: 0-order allocation failed (gfp=0x30/0) Feb 25 03:05:17 sheep kernel: This architecture does not implement dump_stack() Feb 25 03:05:27 sheep kernel: __alloc_pages: 0-order allocation failed (gfp=0x30/0) Feb 25 03:05:27 sheep kernel: This architecture does not implement dump_stack() Feb 25 03:05:27 sheep kernel: __alloc_pages: 0-order allocation failed (gfp=0x30/0) Feb 25 03:05:27 sheep kernel: This architecture does not implement dump_stack() Feb 25 03:05:27 sheep kernel: __alloc_pages: 0-order allocation failed (gfp=0x30/0) Feb 25 03:05:27 sheep kernel: This architecture does not implement dump_stack() Feb 25 03:06:17 sheep syslog-ng[324]: STATS: dropped 94 Feb 25 03:07:42 sheep kernel: __alloc_pages: 0-order allocation failed (gfp=0x30/0) Feb 25 03:07:42 sheep kernel: This architecture does not implement dump_stack() Feb 25 03:07:52 sheep kernel: __alloc_pages: 0-order allocation failed (gfp=0x30/0) Feb 25 03:07:52 sheep kernel: This architecture does not implement dump_stack() Feb 25 03:07:52 sheep kernel: __alloc_pages: 0-order allocation failed (gfp=0x30/0) Feb 25 03:07:52 sheep kernel: This architecture does not implement dump_stack() Feb 25 03:07:52 sheep kernel: __alloc_pages: 0-order allocation failed (gfp=0x30/0) Feb 25 03:07:52 sheep kernel: This architecture does not implement dump_stack()
for the record:
root@sheep:~# cat /proc/sys/vm/vm_gfp_debug 1 root@sheep:~#
some thoughts of mine: after setting vm_gfp_debug to 1 i run the benchmarks again, with a 200MB testfile (within a 700MB fs, setup via cryptoloop). in the log the messages from above showed up, but this time the benchmark was able to finish, the system was *never unusable* during the test (like i was experienceing with former kernels too). but: i don't know if i had another memory consuming app running last time. even if i did, i did not get any OOM messages, but i could think of higher memory- / vm-pressure last time....
oh, and just in case i forgot last time, this is the machine: http://nerdbynature.de/bits/sheep/2.4.24-benh/ver_linux
(maybe this is why syslog says: " Feb 25 03:07:52 sheep kernel: This architecture does not implement dump_stack()"?)
Thank you, Christian. -- BOFH excuse #141:
