Hi,

 Mihai is trying to setup a small Pss machine that also works as a cache.

 For reading it seems to work fine, yet it stubbornly refuses to write files with
this error:

 If we remove the directive pss.cachelib then writes work instead.

 Can anyone give us a clue please ?

Thank you
Fabrizio and Mihai
