I did inspect the code, and saw more closely where the problem seems to be.
An unknown client do some file system access, then ltspfsd tries to mount the device, because the device is still listed in /var/run/ltsp_fstab. Then, the script /usr/sbin/ltspfs_mount detect this condition, and call /lib/udev/ltspfs_entry remove, to clean the mount point from fstab. At the same moment, udev triggers the remove event, and also call the script /lib/udev/ltspfs_entry remove. Both script instances hang on "lbmount --umount". -- ltspfsd hang while removing usb key without LDM https://bugs.launchpad.net/bugs/378495 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
