Sandbox operation environment detection method and device

The invention provides a sandbox operation environment detection method and device. The detection method comprises the steps that after a notification message of collapse of a server sandbox operation environment is detected, a Task manager of a server sandbox receives multiple first requests which establish connection and are sent by all application programs coming from a client sandbox; based on the first requests, the Task manager of the server sandbox establishes multiple first connection relations with all the application programs in the client sandbox; based on multiple first connection relations, the Task manager of the server sandbox receives related data, sent by all the application programs in the client sandbox, in all task tables; based on the related data in the Task tables, the operation state of the server sandbox is recovered to the operation state before collapse. By means of the sandbox operation environment detection method and device, the condition that a user can accurately and rapidly re
