Resolver o erro You server terminated the import process

Gente se alguém puder ajudar estou usando o plugin All Import

Eu cadastro propriedades em um site chamado Value Gaia, o plugin ele acessa um xml criado pelo value gaia e baixa todas as propriedades para dentro do meu wordpress, o problema e que o servidor interrompe a conexão e não termina o import, ele me da a opção de ficar tentando varias vezes até quebrar de vez.

Já mexi no php.ini pra aumentar o max_execution_time, define pra 300 que é o que a documentação falou que poderia resolver, aumentei

post_max_size = 500M
upload_max_filesize = 500M
memory_limit: 512M
max_input_time: 60
max_file_uploads: 20

e nada adiantou, na documentação ele fala que pode ser também um erro no apache, mais como e da locaweb e é compartilhado nem eu nem eles podem mudar, a documentação fala pra mudar assim

FCGID Timeouts (Apache): This is set in httpd.conf with FcgidIOTimeout. This is set in httpd.conf with FcgidIOTimeout. It determines how long mod_fcgid will wait while trying to perform a read or write. It should be set as high as your host will allow. In our experience 90 seconds is sufficient.

mais não e possível na locaweb.

esses são os erros que ele fica retornando na tela a cada tentativa
