Once again ...
hi folks,
we are suffering under a problem, wich hits us a couple of times a month.
It's a quite loaded (CP1) firewall system running Linux 2.2.20 with Donald's
v0.94 network drivers.
It has lots of free memory (~128m) and the CPU (p3 500Mhz) load is below 1%
!
There are 2 ZNYX zx364 (4 Port 21143) and 2 Intel eepro100 installed.
All ports running fixed 100 full-duplex with CISCO 5500/3500 Catalyst.
Well sporadically we encounter those "transmit timeout" message(s) on the
Znyx ports and the traffic stuck at once until we "restart" (ifdown
ethx;ifup ethx) the interface. The "link" still exists (card LED's, switch
port status).
Since we are not able to interpret this strange driver status messages, we
need some help?!
Ok, we don't have the tulip-diag output of the "hang-up" yet, but if it
happens again, we will save a tulip-diag -ae.
Anyway if any of the provided information allow a diagnose of the problem,
pleas let us know (also if something else is needed).
thanks in advance,
Klaus
