mysqltest: At line 67: query 'connect  con3,localhost,root,,' failed: 2003: Can't connect to MySQL server on 'localhost' (0 "Internal error/check (Not system error)")

The result from queries just before the failure was:

CREATE PROCEDURE p_analyze()

BEGIN

DECLARE attempts INTEGER DEFAULT 100;

wl_loop: WHILE attempts > 0 DO
