Temporary tables will not work if the table with the same name
is used in more than one thread - we plan on fixing this soon. For
now the only thing you can do is turn off logging of the trouble
queries with @code{SET SQL_LOG_BIN=0}
Temporary tables starting in 3.23.29 are replicated properly with the
exception of the case when you shut down slave server ( not just slave thread),
you have some temporary tables open, and the are used in subsequent updates.
To deal with this problem, to shut down the slave, do @code{SLAVE STOP}, then
check @code{Slave_open_temp_tables} variable to see if it is 0, then issue
@code{mysqladmin shutdown}. If the number is not 0, restart the slave thread
with @code{SLAVE START} and see
if you have better luck next time. There will be a cleaner solution, but it
has to wait until version 4.0.
In earlier versions temporary tables are not being replicated properly - we
recommend that you either upgrade, or execute @code{SET SQL_LOG_BIN=0} on
your clients before all queries with temp tables.
