I installed Zentyal on a HP Proliant Microserver (AMD 64bit processor). If for an accident I disconnect any USB peripheral (I have a mouse, a keyboard and some times an USB HD) without unount it the server will shutdown. Seems that the server shutdown correctly but I have an application (Atlassian JIRA) that doesn't shutdown properly so I need to repair it if I disconnect (uncorrectly) the USB peripherals. Is this normal?
