Transaction stuck in Pending in Private Network

Hello

I am currently running a private network, testing some values in the consensus.json. Everything is working fine until I do a test of sending many maxed transactions(txns). About 9 to 10 MB of transactions the payload of note field is full.

When I check the pending txns in my relay it says 0 but when I check the node it tells me there 60 txns in pending. Any other transaction I send from the same node goes through normally, but those 60 txns are stuck in pool until I restart the node. What can be the cause of this? My assumption is backlog of txns which I see in source code is set to 1000.

Any hints or pointers I get would be appreciated.
Thanks

Can you post your consensus.json?

Hello, thank you for answering.
Here you can see it.

Most modification are Max block size and Note field.
