# Relayer problem and question

### Relayer fee problem
It cost so much fee to relay because we submit msg update client in per block. It's about 10k for 30 minutes relay.

### Stuck when relay from cosmos -> picasso
- Relayer tries to submit MsgRecvPacket in Picasso but got this error :

message: Ics04ChannelSubdetail { 
    source: AppModule(AppModuleSubdetail { 
        description: StringTracer: implementation specific error: [on_recv_packet] AcknowledgementError {n    
            msg: Some(n        
            Failed to validate acknowledgementStringTracer: Packet acknowledgement exists for the packet with the sequence 2),
        } 
    }
)}

Trying to run `hyperspace fish` but got this err :

## Timeout packet
How to timeout packet ?
When relaying, I see 3 stuck packet(I set timeout when transfer is 10minutes) but relayer didn't timeout this packet.

### How to relay next packet if relayer got problem when submit previos packet ?

### Misbehaviour handling ?
