Description

The gRPC module has a potential bug that causes a crash:

fatal error: concurrent map iteration and map write

This is likely due to unsafe casting of the SentBytes and ReceivedBytes maps, leading to concurrent map iteration and map write:

pactus/www/grpc/network.go

Lines 111 to 112 in 34f0b99

    
           SentBytes:           *(*map[uint32]uint64)(unsafe.Pointer(&sentBytes)), 
        
           ReceivedBytes:       *(*map[uint32]uint64)(unsafe.Pointer(&receivedBytes)),

The text was updated successfully, but these errors were encountered:
