network & samba trouble..

[Igaduma]

Hi all,

I got an ultra 10 running as fileserver at 100fdx with an external discpack, i'm using samba 2.2.2 and standard NT4 sp6 clients, drivemapping name-to-ip resolution is done via /winnt/system32/drivers/etc/hosts file
All goes well for a few minutes, cpu at 80%, iostat looking ok, no blocking, vmstat seems clean and top seems to report heavy, but acceptable usage & load.
Note that i'm ftping with 5 clients, all at 100fdx.
Then all of sudden *all* network activity stops and the machine can't even be ping-d on the same subnet.
Then the weirdest thing happens:
I type snoop to check the network packets and whatdaya know, the machine comes up again and continues file-serving over ftp & samba goes back on-line.

what the heck is wrong ?

btw, router is configured at 100fdx & so is the machine, not using autoneg.

please help.....i'm silently dying here, went live with oracle db & application, now bottleneck is this problem...each time the disk stops grinding, i type snoop and all continues....


Thanks.

I WISH!!

No, I think it has to do with some sort of either saturation or half-full duplex issue.
Copied the bulk of static files to local machines, disabled the wins server that was contacted on another subnet.
Seems to be OK today..
