这里是从Lustre的入口导致的oom，但实际上，其他入口例如KVM管理程序也可能引起oom，即任何分配内存的可能点都可能引起oom。
从分析过程来看，确实是Lustre的Cache占用了大量内存，导致内存分配不足。
三个措施。1、增大内存从12GB增大到16GB。virsh setmaxmem vgfsxxx 16GB --config运行启动后virsh setmem vgfsxxx 16GB这个没有用，跑了几次测试后，仍然掉服务。
2、调整lwfsd的服务优先级设置lwfsd的服务优先级为“-17”PID=`ps | grep lwfs | grep -v grep | awk '{print $1}'`echo -17 & /proc/$PID/oom_adjecho -17 & /proc/$PID/task/$PID/oom_adj这个好像有用。
3、修改内存分配策略并且echo "2" &/proc/sys/vm/overcommit_memory，使得分配内存时，必须存在足够的空间用于映射。这个好像也有一定的用处。再跑跑试试。
