This problem seems to happen at random. It has happened a few times out of the blue for no apparent reason but the easiest way to make it repeat itself is to do an Rdump down the Ethernet from a remote machine. This isn't a sure-fire way of forcing it to hang but will do the job nicely 50% of the time. When it does happen, all current connections through that board are lost. The output error count as reported by `netstat -i' climbs rapidly. Unfortunately, a reboot is the only known solution. Very rarely, the console also prints the message il0:stray xmit interrupt, csr=ffffffd0 One further point worth mentioning is that we have installed the fixes to /sys/netinet/tcp_input.c (circa lines 308 and 390) as recommended by Andrew Russel of Sun UK (sunuk!ar) and which are supposed to solve a similar problem (losing connections when rdumping Sun to Vax). In practice, though, these fixes don't seem to make any difference. The system is a (almost) vanilla 4.2bsd Vax-11/750 with 3MB, UDA-50, RA-80, RA-81, TU-78, DZ-11, VMZ-32 and NI-1010A. The remote machine (being rdumped) is a Sun-2/120. If anyone has any idea or knows of the cure for this problem, please let me know. (If anyone also knows a way of restarting the Ethernet board without resorting to a reboot, that would also be extremely useful information). All help will be very gratefully received. Many thanks in advance, Cheers, Robert. ****************************************************************************** Robert Ward, ___________ Hasler AG, Murtenstrasse 137a, CH-3008 Bern, Switzerland | _ | | _| |_ | Tel.: (+41) (31) 65 23 19 | |_ _| | Bitnet: hslrswi!robert@cernvax.bitnet | |_| | Arpa: hslrswi!robert%cernvax.bitnet@WISCVM.ARPA |_________| Edunet: hslrswi!robert%cernvax.bitnet@UCBJADE.Berkeley.EDU Uucp: ... {seismo,decvax,ukc, ... }!mcvax!cernvax!hslrswi!robert ******************************************************************************
