TCPConnectionManager error "Reason: Connection pending send bytes is too large"

We appear to be hitting some sort of threshold in the TCP connections on our EventStore box which appears to be causing closed connections. This box is running EventStore v4.1.0.0. I’ve upsized the server to make sure we are not resource starved and we currently have plenty of memory and CPU runway, based on the current utilization. Can anyone give direction on the following error that is consistently showing in the error log:

Pending send byte being too large means the client is not keeping up with the data requested. EG the client’s queue just is growing

as example 15686412 is the size in bytes of things queued to be sent to the client.

Thank you for the reply. That makes sense…so essentially our client nodes are asking for more than they can process in a timely manner, and we are exceeding the threshold which triggers the closing of a backlogged connection?
It sounds like strategies going forward would be: reducing call rate from the clients, reducing the size of the requests, and possibly increasing resources on the client nodes to improve processing speed.

Most likely it is request sizes / network performance. Are you doing lots of reads? What is your read window size? Do you have some very big events that may trigger this? What does the networking environment look like?

The closing is actually a self defense measure against possibly malicious clients.How many MB are reasonable to keep in memory of unsent yet pending data? If not capped a malicious client could take down the server by issuing many requests and being deliberately slow handling responses.
