from a month I purchased a VPS with Centos 6 and Plesk 11.0.
Since a few days (more often) happens that I get an email from cron plesk and all the sites with a mysql db fall with the error.
SQLSTATE[HY000]: General error: 1 Can't create/write to file '/tmp/#sql_2a4_0.MYD' (Errcode: 17)
I checked and it's not a permission problem (mysql user is able to write without problems), I thought it was a problem of "numfiles" but since the problem persists even when it's below this limit and also manifests itself only ever temporary files to mysql, I tried to replace tmp folder with another, but problem it's still here (if possible even more frequently).
I do not know which way to turn...
Can you help me?
