Dear list,

I'm still struggling to get the Cyclades 8Y up in production.

Latest is the following panic (panic("receive 1");):

in sys/kern/uipc_socket.c: about line 628

This seems to happen when a PPP session is active, and under load.
In this case, the ethernet/TCP is loaded fairly heavily - (two FTP
sessions actively transferring data to another local machine) and
there is a large file copy is going on. (about 30 Mbytes from SCSI disk
to SCSI disk)

Can anyone tell me what this panic means?  Is this "DIAGNOSTIC" a debugging
thing that can be/should be turned off?

A little bit of guidance would be helpful to my debugging.

Thanks in advance,
