Ok guys, here´s the problem... I upgraded to Plesk 9.2.1 and found that between the security upgrades they moved all the contents of /usr/local/psa/handlers to tmpfs, the problem is that I have a small swap file ( about 500 MB ) so all thos folders got inside that space, so far I´ve managed to make the tmpfs more than twice the original size, but mounted points ( /usr/local/psa/handlers/spool ) remains at the same size of 500 MB any idea how can I make this larger?
