I upgraded to ISPConfig ver 2.2.27 last week and all seemed to go well. Today I was optimizing my large vBulletin MySQL database and it got hung on the post table. The problem was that my /tmp was 100% full. The largest files I found in /tmp were the backup files left over from last week's ISPConfig upgrade. Once I deleted them I could optimize my MySQL databases without issue. Should these files be manually deleted after each upgrade or are they supposed to automatically be deleted upon completion of the upgrade? Thanks!
