It would be useful to register an OOM callback in Lustre using register_oom_notifier() (and deregister at shutdown with unregister_oom_notifier(), firstly in libcfs and obdclass to print the current libcfs_kmemory and memused_show()/memused_max_show(), as well as potentially trying to shrink caches (e.g. the number of LNet message buffers, debug logs, etc.) before a userspace process is killed.
