It appears that the trap is caused by nfsd. I keep nfsd on with the following configuration: rpcbind_enable="YES" nfs_server_enable="YES" mountd_flags="-l -r" mountd_enable="YES" nfs_client_enable="YES" rpc_lockd_enable="YES" rpc_statd_enable="YES" autofs_enable="YES" But the trap condition persists regardless of whether there is a client or not. I also attach a kgdb session log. -- You are receiving this mail because: You are the assignee for the bug.home | help
