Lost connection to MySQL server at 'reading initial communication packet'

[netzartist]

Hi,

on a client website I've enabled error notification and sometimes I receive such mails with this message:

Page: http://www.domain.com/?/
User: ?

Error: 
Exception: SQLSTATE[HY000] [2013] Lost connection to MySQL server at 'reading initial communication packet', system error: 111 (in /kunden/bla/wire/core/ProcessWire.php line 143)

What does this mean? Is this normal? Or a kind of hacking attempt? Anything I can do to prevent this? Or just ignore it? ...

Thanks

Jan

I'm not an expert, but I think a server problem is likely the answer, either a misconfiguration or something broken. Has this happened more than once?

I'd be inclined to contact my hosting company if I were you.
