7 years ago Thanks for reporting!
That’s not an age limit, it’s just we restarted our Bitcoin node two days ago. Currently the node sees the same number of transactions in the mempool as our main database.
I guess the difference in numbers comes from the fact that some older and/or low fee transactions are stopped from being relayed at some point.

7 years ago I have a 3 transactions in the mempool (generated @ height 479917), that do not show up blockchair, but show up on blockchain.info. My node is fairly well connected and has re-transmitting the transactions since I created them (with way too low of a fee).
Could you be filtering out old mempool transactions based on locktime? I noticed my transactions do have locktime set to 479917?

7 years ago No, we are not filtering transactions in any way. It also doesn’t seem like the problem is with locktime: https://blockchair.com/bitcoin/mempool/transactions?q=block_id(-1),lock_time(1..)#
Maybe the problem is that we are running Satoshi:0.12.1. We’ll investigate the issue further.

6 years ago While introducing support for SegWit we’ve upgraded our Bitcoin node, so I hope it should now see more transactions.
In the future we’ll be using multiple nodes to collect as many mempool transactions as possible.
My node running Satoshi:0.14.2 currently (block height 480326) shows 9889 transactions in the mempool, but https://blockchair.com/bitcoin/mempool/transactions only shows 7206.
I'm not sure what filter rules you are using, but I would assume it should be the same as bitcoin core out of the box.
(It looks like you have an age limit of about 2 days, but with the current state of the mempool transactions are getting stuck in the mempool for much longer then that)
