Hi,

I first noticed this problem on machines with more memory (32GB eg.), 
but now it happens on 4G machines too:
tmpfs                                       0B      0B      0B   100%    
/tmp

Maybe it's related, that I use zfs on these machines...

Sometimes it grows and shrinks, but generally there is no space even for 
a small file, or a socket to create.
