Moreover, I can see that /dev/shm mounted with tmpfs type: linux-2.6.34-gentoo-r6 # mount /dev/sda3 on / type xfs (rw,noatime) proc on /proc type proc (rw,nosuid,nodev,noexec,relatime) sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,relatime) udev on /dev type tmpfs (rw,nosuid,relatime,size=3D10240k,mode=3D755) devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=3D5,mode=3D620) shm on /dev/shm type tmpfs (rw,noexec,nosuid,nodev) usbfs on /proc/bus/usb type usbfs (rw,noexec,nosuid,devmode=3D0664,devgid=3D85) /dev/sdb2 on /mnt/nilfs2 type nilfs2 (rw,gcpid=3D6331) And it is possible to see it from strace output also (tmpfs magic - 0x1021994): statfs("/dev/shm", {f_type=3D0x1021994, f_bsize=3D4096, f_blocks=3D64251, f_bfree=3D64250, f_bavail=3D64250, f_files=3D64251, f_ffree=3D64249, f_fsid= =3D{0, 0}, f_namelen=3D255, f_frsize=3D4096}) =3D 0 However, I have not last stable kernel on its machine (2.6.34-gentoo-r6). Maybe, it can make some side effects. I am going to continue investigation of the issue. I attach to the e-mail full strace output (10-07-2012-nilfs-cleanerd-issue.txt). With the best regards, Vyacheslav Dubeyko.
