File copy: svr2008->svr2008 causes 3550 to crash; all IOS
I've had a 3550 running on 12.1 with a single windows server 2008 machine (and a bunch of XP, 2003 and linux as well) for a while with no problems. Today I added a second windows 2008 server and when I try and copy large files across the 3550 between the 2008 servers it crashes the 3550 with a "Software Forced Crash Exception (0x0700)!" (sho tech attached) I upgraded the 3550 IOS to 12.2.44SE3 and get same results. I can repeat this at will.
I haven't sniffed a capture yet but it happens immediately in the first few kilobits (or less). There is clearly something going on between the 2 windows 2008 machines causing it that doesn't take place among the other pairs. I can copy the same files between any other pair of OSs without the crash.
(a 1.7G ISO is the file I first noticed this with)
I swapped NICs in the new 2008 machine thinking it was flow control or something but even with the second NIC its the same.
I tried different ports with no custom config with same results.
The first server 2008 is on 0/6; an IBM365 the new 2008 is on 0/1; a generic ASUS P4D. The NICs tried were the onboard SIS100M and an Intel PCIE Dual 1000MT.
Any thoughts? Does Windows 2008 send some sort of propritary discovery packet only when speaking to another 2008 server that bombs the Cisco? What's up?
There must be something wrong with the IOS code right?
This one is wild and puzzling me and I'll try almost anything requested to solve it.
