@chenchengfa93 thanks for reaching out and reporting this issue.

We noticed you're using gRPC version v1.59. The current version is v1.66.2, which includes several bug fixes and performance improvements.

Could you please upgrade to the latest version and see if the issue persists?

If the problem continues after upgrading, please provide a reproduction test case so we can investigate further. The information provided so far isn't enough for us to debug effectively. This will help us pinpoint the exact cause of the error and provide a faster resolution.

@eshitachandwani thanks for reply

I will try to upgrade to the latest version based on your suggestion.

But the frequency of this problem is very low, and I may not be able to reproduce it.Do you have any helpful suggestions for reproducing it
