FSC node can continue to call

Constantly calling FSC node will eventually leak memory

[adecaro]

@yaofeiliang , very interesting catch. Which FSC commit are you using?
We fixed a similar issue in the past.

[yaofeiliang]

@adecaro Thanks for your reply, I will first pull the latest main branch code to see if it can solve my problem.

[yaofeiliang]

@adecaro I ran the iou example of the latest branch of main, and the error still exists

[adecaro]

@yaofeiliang , thanks much for your feedback. I will look at it ASAP.
I remember that last time we had to adjust certain GRPC settings.

What is puzzling me though is that what stopped working was the chaincode but the chaincode talks to the Fabric peer not the FSC directly.
Therefore, can it be the related to the GRPC setting of the fabric peer?

[GeorgeNiotis]

any luck with that error?
I'm gettin this kind of error after running caliper benchmark tool
