It recently got upgraded to 4.3 from 4.2, and now it is having problems with the TX buffer somehow on the network card. Every once in awhile it will shut off all network traffic and give these errors: no memory for tx listrl0 Then in a few minutes (presumably when the buffer is flushed somehow) the network device resumes normal operation. We have tried 3 different NICs, and all have had the same problem. The three models were: 1. Realtek RTL8139A 10/100TX 2. Intel chipset:82558B 3. 3Com somethingerather. We are running with 512MB of RAM, and it usually has about 200 or more megs free at the time of this occurance. Is this a problem with the network drivers in 4.3? Or something else that can be corrected? (Manual way to flush the network card buffers??)
