Unable to find shared memory region problem

[sofiawu]

Description
We deploy GPU services using tritonserver 21.12 version. The service adopts a dual docker mode, with one docker for the logical service and another docker for the triton service.
Data communication between GPU and CPU is done through shared memory
Recently, we have found that our service encounters an error like
tritonclient.utils.InferenceServerException: [StatusCode.NOT_FOUND] Unable to find shared memory region: 'data_xx_x'
causing the triton service to be unavailable and all service requests to fail.
After restarting the service, it resumes normal operation.
