Eu sei que quando o Windows processa arquivos abertos para leitura, eles os bloqueiam. Como o indexador do Windows faz isso? Pode impedir que o arquivo seja excluído além de atrasar tudo? Meu script pode desativar a indexação na pasta de trabalho ?
Eu me pergunto porque usamos arquivos para comunicação entre processos . Eu monitora quando o arquivo to.ugp é excluído. Isso funciona muito bem somente na máquina em que o indexador de pesquisa está desabilitado. Eu organizei os registros com filemonitor :

Você vê que java.exe: 2484 é um processo produtor e pesquisa o arquivo to.ugp até que ele exista com a intenção de criar um novo quando o arquivo for excluído pelo consumidor. java.exe: 5812 é o consumidor. Ele lê o arquivo no início do rastreio e deixa de existir. Então java.exe: 2484 polls - o arquivo ainda existe. Então, novo consumidor é criado. Deve remover o arquivo consumido anteriormente. Mas SetDispositionInformationFile resulta com erro "CANNOT DELETE". Por quê? Vejo que o SeachHost abre o arquivo antes que o novo consumidor o feche. O arquivo nunca será excluído e java.exe:2484 pesquisará apenas no final.
Eu também rastreei os acessos anteriores ao arquivo (pode ser que ele te ajude a dizer o que causou o erro?):

O monitor de arquivos não informa a causa do erro. Ele informa que SearchProtocolHost abriu o arquivo após a tentativa fracassada de excluí-lo. Mas, pode ser o filemonitor apenas relata os eventos de arquivo fora de ordem? Poderia SearchProtocolHost ter aberto o arquivo apenas segundo antes e impedir a exclusão, apesar do relatório do monitor de arquivo?
Eu removi a indexação da minha pasta , mas ainda estou recebendo

acontece um após o outro e meu processo de java falha porque não pode remover o test.bin . Não vejo mais ninguém além do SearchProtocolHost que acessou esse arquivo. Por que ninguém relata que o SearchProtocolHost bloqueia os arquivos mesmo depois que a indexação foi desativada?
Atualizar Corrigi o problema tentando repetir a exclusão. A segunda exclusão imediata é bem-sucedida. Por exemplo, aqui está um perfil de novas tentativas (a primeira coluna são os segundos)

21764: evaluator\to.ugp
22318: evaluator\to.ugp

do processo do produtor. Nós vemos uma falha a cada 30 minutos. Meus processos são single-threaded. Não pode ser que um dos meus threads libere o bloqueio para que a exclusão seja bem-sucedida. No entanto, se eu remover a computação e deixar a E / S de arquivo simples, nenhuma falha de exclusão será observada e isso nunca ocorreu comigo com outros aplicativos java.
Apesar de eu ter resolvido o problema, perguntei se os serviços do Windows (índice de arquivos, antivírus) podem ser culpados e ainda aguardar a resposta. Por que a exclusão falha? Por que eu ainda posso confiar em file open e file.exists () sem nenhuma tentativa?
update-2
A resposta está correta . MsMpEng é reconfiável. No entanto, eu me pergunto como ele consegue mapear o arquivo depois que o CreateFile falhou nos meus logs acima. Eu também tenho visto que o realplayer faz isso ( Windows XP, RealPlayer 15.0.1.13, RealNetworks, Inc., Build time: Wed Nov 30 02:07:39 2011 command line: "c:\program files\real\realplayer\RealPlay.exe" /runevent "C:\program files\real\realplayer\update\upgr3270.dll" AutoUpdateEvent ) em outra máquina.
