Looks to me like tmpfs is full and maybe too small.
http://wiki.galaxyproject.org/Admin/Config/Performance/Cluster?highlight=%28temp%3D%29 eg suggests setting $TEMP= somewhere sensible. 
But that's not always enough depending on the third party executables you're running so you might want a bigger /tmpfs too.

Possibly not enough space left on the volume being used for temporary files.

What does
df
show?

Hi all,
 
When I added a dataset in the Manage data libraries, galaxy reported some erros. Anyone knows what's wrong?
