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...
const uint256 hash(pblock->GetHash());
        {
            LOCK(cs_main);
            
            
            forceProcessing |= MarkBlockAsReceived(hash);
            
            
            mapBlockSource.emplace(hash, std::make_pair(pfrom->GetId(), true));
        }
        bool fNewBlock = false;
        ProcessNewBlock(chainparams, pblock, forceProcessing, &fNewBlock);
        if (fNewBlock) {
            pfrom->nLastBlockTime = GetTime();
        } else {
            LOCK(cs_main);
            mapBlockSource.erase(pblock->GetHash());
        }
        return true;
    }
    if (strCommand == NetMsgType::GETADDR) {
        
        
        
        
        
        if (!pfrom->fInbound) {
            LogPrint(BCLog::NET, "Ignoring \"getaddr\" from outbound connection. peer=%d\n", pfrom->GetId());
            return true;
        }
