-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 We are having a problem with our mail server. 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??) Here is the output of ulimit -a, just in case that helps. core file size (blocks) unlimited data seg size (kbytes) 524288 file size (blocks) unlimited max locked memory (kbytes) unlimited max memory size (kbytes) unlimited open files 65536 pipe size (512 bytes) 1 stack size (kbytes) 65536 cpu time (seconds) unlimited max user processes 531 virtual memory (kbytes) 589824 This is on a production system which supports around 10,000 users, so any help would be appreciated.
