@ -20067,6 +20067,11 @@ variable. @xref{SHOW}. If this variable is big and you don't do
@code{FLUSH TABLES} a lot (which just forces all tables to be closed and
reopenend), then you should increase the value of this variable.
Make sure that your operating system can handle the number of open file
descriptors implied by the @code{table_cache} setting. If @code{table_cache}
is set too high, @strong{MySQL} may run out of file descriptors and refuse
connections, fail to perform queries, and be very unreliable.
For information about how the table cache works, see @ref{Table cache}.
