the oom_adj is -17 and oom_score_adj is -1000 after installing device-mapper-multipath-0.4.9-53.el6.x86_64 and starting multipathd.
|
|
This means multipathd will never be selected to be killed by oom according to the kernel doc.
|
|
|
|
|
|
Here are the steps to reproduce this issue.
|
|
1. create a multipathed disk /dev/mapper/mpathb via scsi_debug using all the free memory. this will consume most of the free mem.
|
|
2. io stress on the multipath disk, this step is option.
|
|
#dd if=/dev/zero of=/dev/mapper/mpathb &
|
|
3. consuming the free mem
|
|
#for i in `seq 10000`; do array[$i]=$(</var/log/messages); done &
|
|
4. trigger the oom_killer manually
|
|
#while true; do echo f > /proc/sysrq-trigger ; done
|
|
5. check the console or /var/log/message if multipathd is killed
