English: I suspect that the problem is that safe_mysqld don't return=20
until mysqld ends.
Try to execute safe_mysqld in background in the shellscript:

	if ! pgrep mysqld
	then
		/usr/bin/safe_mysqld &
	fi=09
=09
Castellano: El problema debe ser que no termina safe_mydqld hasta que n=
o=20
termina mysqld. Se podr=EDa solucionar llamando a safe_mysqld en=20
"background" de la forma anterior.
