I am uploading a snoop from the server to http://distfiles.genestate.com/snoop.zip Please note this snoop will include traffic to ssh as I can't work out how to filter that out :P > Normally it would not be too important where the capture was obtained, > but here, where something strange is happening, it could be critical to > understanding what is going wrong and where. > > It would be interesting to do two separate captures - one on the client > and the one on the server, at the same time, as this would show if the > switch was causing disruption.

On another note, I've just moved the offending network to another switch and it's even worse I think. I've noticed that under high load, the link light for the server's connection blinks on and off, not quite steadily but about every 2 seconds. This appears in /var/adm/messages: Oct 29 18:24:22 exodus mac: [ID 435574 kern.info] NOTICE: rtls0 link up, 100 Mbps, full duplex Oct 29 18:24:24 exodus mac: [ID 486395 kern.info] NOTICE: rtls0 link down Oct 29 18:24:25 exodus mac: [ID 435574 kern.info] NOTICE: rtls0 link up, 100 Mbps, full duplex Oct 29 18:24:27 exodus mac: [ID 486395 kern.info] NOTICE: rtls0 link down Oct 29 18:24:28 exodus mac: [ID 435574 kern.info] NOTICE: rtls0 link up, 100 Mbps, full duplex Oct 29 18:24:30 exodus mac: [ID 486395 kern.info] NOTICE: rtls0 link down Oct 29 18:24:31 exodus mac: [ID 435574 kern.info] NOTICE: rtls0 link up, 100 Mbps, full duplex I think it's got to be the NIC, the network runs full duplex quite happily so I don't think its an auto-neg problem. Thanks for sticking with this :) Matt
