Abnormal website database growth I migrated my site to the production  server about 3 months ago . 2 weeks ago , I noticed that the db was growing too fast(about 40Gb I could not account for) I backed the site , deleted WAMP and restored the site .

Result , slower until within the 2 weeks ,it has grown to a halt . Keeps on "connecting ". 
One other thing( could be related ) the site counter is showing a growth of about 1,000 users anonymous users very hour - this is not possible given the site is either too slow or not working at all outside the LAN
I suggest truncate watchdog table, usually this table growth very quick.( maybe you can first  get a backup of this table then truncate(empty) it)

( maybe trucnate cache tables be useful but If you see table size u will see the watchdog have biggest size )
