No space on tmp but is empty

Hi

I have following error message

/home/morta/.cache/yay/anbox-git/src/anbox/external/android-emugl/host/tools/emugen/ApiGen.cpp:1392:1: fatal error: error writing to /tmp/ccvbFAZi.s: No space left on device

but du -shc /tmp gives me a filesize of 18k and I have 64GB RAM

and on /etc/fstab is

# /tmp
tmpfs		/tmp	tmpfs	nodev,nosuid	0	0

The driven is not even full but I can't build also not new initramfs because of this failure or push a git from AUR to the tmp folder. It's like full but I don't know why.

How I can fix this?

Cheers

Re: No space on tmp but is empty

mount | grep tmpfs
df -h

The default is 50% of your RAM

Re: No space on tmp but is empty

Well, there's a bunch of hidden directories you didn't check.

Re: No space on tmp but is empty

Seth, the hidden directories would have been picked up by the `du` command in the first post.

EDIT: but they would have been missed by the `du` command in post 3.  Was the du command in post 1 run as root?  Perhaps each one missed some files.  What's the output of the following as root:

du -shc /tmp

Re: No space on tmp but is empty

stale filehandles to unlinked files.
Some process will have files opened in /tmp that are removed from the FS, but can't be freed.
A reboot would free the space.

sudo lsof -a +L1 /tmp

a ton of wdfs file reservation. How I can say that wdfs don't use all tmp space?
