erros do MySQL com Drupal e MediaTemple

Question

Tenho tido problemas intermitentes entre o drupal 7.14 e o MediaTemple. Especificamente estou recebendo este erro:

PDOException: SQLSTATE[HY000]: General error: 1205 Lock wait timeout exceeded; try restarting transaction: SELECT revision.order_number AS order_number, revision.revision_id AS revision_id, revision.revision_uid AS revision_uid, revision.mail AS mail, revision.status AS status, revision.log AS log, revision.revision_timestamp AS revision_timestamp, revision.revision_hostname AS revision_hostname, revision.data AS data, base.order_id AS order_id, base.type AS type, base.uid AS uid, base.created AS created, base.changed AS changed, base.hostname AS hostname FROM {commerce_order} base INNER JOIN {commerce_order_revision} revision ON revision.revision_id = base.revision_id WHERE (base.order_id IN (:db_condition_placeholder_0)) FOR UPDATE; Array ( [:db_condition_placeholder_0] => 75 ) in DrupalDefaultEntityController->load() (line 196 of /nfs/c03/h01/mnt/81976/domains/wgsource.com/html/includes/entity.inc).

Foi-me dito que o MT alterasse o tipo de tabela para o MyISAM, e que havia um problema entre eles e o drupal. (veja o comentário # 23 aqui ). Isso não corrigiu meu problema. Eu tenho um contêiner de grade com eles, e o relatório e a configuração são os seguintes. Especificamente, estou preocupado com o número de linha 39 do relatório do MySQL. O que posso fazer para corrigir isso?

Answer 1

Os engenheiros de MT reconhecem que isso é um problema & forneceu uma correção que pode ser obtida de duas maneiras. O primeiro & O método recomendado é:

1) Faça o backup dos seus dados 2) Remova o Drupal da sua conta 3) Reinstale o Drupal usando a instalação atualizada de 1 clique 4) Importe seus dados

O segundo método não é necessariamente a melhor correção, mas foi testado. Nota: isto não é suportado por (mt).

1) Descarregue o DB inteiro 2) Despeje a tabela de variáveis. "mysqldump -uUser -p variável db1234_drupal > db1234_drupal.variable.sql 3) Mude o 'motor = INNODB' para 'engine = MyISAM' 3. Reimporte sua mesa
