Apesar do log não mencioná-lo, o MySQL perdeu o arquivo errmsg.sys. Isso foi mencionado no visualizador de eventos do Windows. Depois de copiar errmsg.sys, tudo está ok, escravo funcionando corretamente.
Estou tentando mover o MySQL slave do pc antigo para o novo. O escravo original é a versão 5.6.12 do MySQL, igual a um novo escravo (o MySQL é parte do wamp 2.4). A replicação funciona bem na máquina antiga. Mas quando eu paro escravo, copio pasta de dados e my.ini para new e tento iniciar wamp eu recebo:

E tudo isso. Executando o mysqld-debug:

Em seguida, conecto-me ao DB, executando a consulta 'SHOW SLAVE STATUS':
Slave_IO_STATE:Connecting to master
LAST_IO_ERRNO:2003
Last_IO_ERROR:error connecting to master '[email protected]:3306' - retry-time: 60 retries: 5
O firewall está desativado, o IP mestre está disponível (o ping funciona). Eu estou querendo saber, o que está errado - o serviço regular do wamp start falha com nenhum número de erro, o mysqld-debug não pode conectar ao mestre.
O que pode estar errado, quando o escravo roda na vm original sem nenhum problema? Obrigado por todas as respostas.
Você atualizou as concessões para permitir que o novo escravo se conecte?
