&gt; When MySQL runs out of threads (due to OS thread limits, ulimit, or
&gt; connection limits), the root MySQL user can no longer connect.  This makes
&gt; it difficult to impossible to debug or repair the ailing MySQL server. 
&gt; MySQL should reserve a thread for connections by the MySQL `root&#039; user.

Note that we are aware that there is already a thread reserverd in case the max_connection limit is set but this does not work in case of a hit ulimit.

bye,
