ZMQ Errors: tx time is 2.000 ms in the past...anybody seen this before?

[ItsGarand]

I have srsran 4G set up and running on Rocky Linux 9 using the ZMQ virtual radios and a gnuradio-compnaion graph. The first test seemingly ran without any issues using the suggested / out of the box configuration that was outlined in the docs. The EPC, eNb, and UE all ran, the ping test worked, and I got gobs of IQ data in the output sinks. So I guess all good.

When I changed the number of resource blocks to 25 and the sample rate to 7.68e6 (enb and ue) I get the to following error spilling out of the eNb:

[zmq] Error: tx time is 2.000 ms in the past...

Here is the output of the eNb:

CH0 rx_port=tcp://localhost:2100
CH0 tx_port=tcp://*:2101
CH0 fail_on_disconnect=true

This is the output of the ue:

So, the question is why am I seeing the tx time errors and where is the sample rate of 5.76 coming from?

NOTE: I don't see this issue when I set the number of resource blocks to 15 and the sample rate to 3.84e6

There was a topic similar to this in the mail archives, but I did not find the solution...
