Perhaps this is driver related, but after a few hours (sometimes a day) of network activity, all tcpip activity becomes sluggish, stalling on every connection regardless of where the machine is (even across campus, which has an FDDI ring). This occurs regardless of time or network utilization.
Restarting the network stack by stoping and restarting the network system in (redhat 5.2) /etc/rc.d/init.d/network clears the problem up for an hour or two (transfers that would take 5-6 hours finish in a few minutes).
Running Redhat 5.2, Linux kernel 2.2.0-final, though this has been a problem for every devel kernel I've used. Ethernet card is an SMC-Ultra EZ (using the smc-ultra driver).
Card is ISA. /proc/interrupts: CPU0 0: 16199749 XT-PIC timer 1: 145707 XT-PIC keyboard 2: 0 XT-PIC cascade 5: 2865297 XT-PIC aic7xxx 8: 3 XT-PIC rtc 10: 1 XT-PIC soundblaster 11: 1477601 XT-PIC SMC EtherEZ 12: 493484 XT-PIC PS/2 Mouse 13: 1 XT-PIC fpu NMI: 0

I don't always get that error message, but I'd bet its related.
