Hi all, I've got a bit of an issue with my system which has manifested
itself a few times while I was playing about and setting it up but now it's
in service I could without it.

Hardware:
SS20 with 2x 150MHz Ross HyperSPARC and 384MB RAM

I'm running 2.0 stable with a non-generic SMP kernel.

The problem is that the system appears to not be able to access swap, after
running a number of intensive tasks (case in point this morning being
compiling Python) I get the following error message and anything that
requires a lot of memory subsequently fails to run:

virtual memory exhausted: Cannot allocate memory

The output of free at the time is as follows:

             total       used       free    buffers
Mem:        351140     332496      18644     178180
Swap:       720892          0     720892

Curiously, dmesg give the following message repeated over and over:

sd1(esp1:0:3:0): unable to allocate scsipi_xfer
sdstart(): try again

...and /var/log/messages contains:

Jan 11 10:31:30 wintermute /netbsd: sdstart(): try again
Jan 11 10:31:30 wintermute /netbsd: sd1(esp1:0:3:0): unable to allocate
scsipi_xfer
Jan 11 10:31:30 wintermute /netbsd: sdstart(): try again
Jan 11 10:31:30 wintermute /netbsd: sd1(esp1:0:3:0): QUEUE FULL resulted in
0 openings

Rebooting the machine gets everything back to normal and the machine runs
quite happily until I try any big compile jobs again.

Anyone got any bright ideas?
