Hi, My server configures NFS-client,and also use cachefilesd.But now the server sometimes goes down.And the connection of the shell has a terminal prompt:" kernel:Kernel panic - not syncing: Fatal exception".So I use shell script to record system log per second.The log display: [kslowd] preemptive burial: OBJ3934 [OBJECT_RECYCLING] ffff880042fdf300 [kslowd] preemptive burial: OBJ4ba0 [OBJECT_RECYCLING] ffff8800e2791cc0 [kslowd] preemptive burial: OBJ4c6c [OBJECT_RECYCLING] ffff8800e1bdea40 [kslowd] preemptive burial: OBJ4ea7 [OBJECT_RECYCLING] ffff8800e07f8140 [kslowd] preemptive burial: OBJ4386 [OBJECT_RECYCLING] ffff8800e64fcd80 [kslowd] preemptive burial: OBJ5c85 [OBJECT_RECYCLING] ffff8800b95d59c0 I don't know whether cachefilesd cause the system stops running. Sincerely waiting for your reply! Thank you! -- Linux-cachefs mailing list Linux-cachefs@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cachefs
