your MySQL is too slow to respond to the requests - 
check your SQL queries and see how you can optimise them.
I've been able to go from queries that look up many
thousands of lines to just a single index query.
change your MySQL engine to InnoDB - or
even better, move to postgresql instead. these
event happen when a table gets eventually too
large for the basic MySQL settings to cope. think
about deleting old records etc.  i
