My system is NetBSD-1.2G/i386, a P60 with 40M ram and two SCSI disks
on a BusLogic controller.

After adding a SCSI tape, another SCSI drive, and another 56M ram
(although the BIOS sees all 96M of it, NetBSD only sees 64M of it),
the system has begun crashing during periods of heavy disk activity.

There were a couple of syslog errors on the screen:

02:00:20 /netbsd: nfsd send error 65
02:01:49 /netbsd: nfsd send error 65
02:02:28 /netbsd: nfsd send error 65

The system is a NFS server.
And then after some undetermined time interval:

panic: bha_init_ccb: can't create DMA maps
Stopped at       _Debugger+0x4: leave

At the "db>" prompt, I typed "trace" and got this (which has been typed
by hand and could have minor errors):

Thanks for any help.

Is this mailing list relayed to a newsgroup somewhere and is that why,
most every time I send mail to this list, I get a new set of spam sent
to me?  How does one put a fake address in using MH to stop that?
