anybody can help us with is??????

it happens at night and now during the day all is ok????

This can be happen, if somebody on the site doing something and the database is not responding. Could be a server fault, restart at the moment, you never know. But is this is going all day long, then try to restart your server.

I just had the SQL service restarted and I am still getting the debug backtrace emails. Any other suggestions?

my server added more ram and it seems to be stabilized
