My forum keep crashing

My forum keep crashing all the time for some reason. This is the messege i get in the email before it crashes.

Database error in vBulletin :
Link-ID == false, connect failed
mysql error:
mysql error number: 0

Anyone elce experienced this before? My forum is actually on its own dedicated server, so i am not sure why it is happning.
