I was messing around with min relay policies and found that under certain circumstances the mempool will accept things, then not relay to any peers.

Example made using wallet:
Transaction of size 6195, fee of 619 satoshis, minrelay of 100 satoshis per kvB. Mempool logic allows it:

```
        // No transactions are allowed below minRelayTxFee except from disconnected blocks
        if (!bypass_limits && nModifiedFees < ::minRelayTxFee.GetFee(nSize)) {
            return state.DoS(0, false, REJECT_INSUFFICIENTFEE, "min relay fee not met", false, strprintf("%d < %d", nModifiedFees, ::minRelayTxFee.GetFee(nSize)));
        }
```
and lets it into mempool

but in net_processing.cpp:

```
                    if (filterrate && txinfo.feeRate.GetFeePerK() < filterrate) {
                        continue;
                    }
```
this gets hit because the computed feerate is insufficient(printing I added):
```
0.00000099 BTC/kB
```

I'm not super at arithmetic so I'm opening this up in case someone has an easy fix. 

let me also get a reproducible test failure with this...
if (!AlreadyHave(inv)) {
                
                
                const auto last_request_time = GetTxRequestTime(inv.hash);
                if (last_request_time <= current_time - GETDATA_TX_INTERVAL) {
                    LogPrint(BCLog::NET, "Requesting %s peer=%d\n", inv.ToString(), pto->GetId());
                    vGetData.push_back(inv);
                    if (vGetData.size() >= MAX_GETDATA_SZ) {
                        connman->PushMessage(pto, msgMaker.Make(NetMsgType::GETDATA, vGetData));
                        vGetData.clear();
                    }
                    UpdateTxRequestTime(inv.hash, current_time);
                    state.m_tx_download.m_tx_in_flight.emplace(inv.hash, current_time);
                } else {
                    
                    
                    
                    
                    const auto next_process_time = CalculateTxGetDataTime(txid, current_time, !state.fPreferredDownload);
                    tx_process_time.emplace(next_process_time, txid);
                }
            } else {
                
                state.m_tx_download.m_tx_announced.erase(inv.hash);
                state.m_tx_download.m_tx_in_flight.erase(inv.hash);
            }
        }
        if (!vGetData.empty())
            connman->PushMessage(pto, msgMaker.Make(NetMsgType::GETDATA, vGetData));
