cnfsstat on *large* buffers under FreeBSD ...

[The Hermit Hacker]

I'm running FreeBSD 3.2-STABLE with Perl:

This is perl, version 5.005_03 built for i386-freebsd

If I run cnfsstat, no args, all goes well:

%bin/cnfsstat 
Class control  for groups matching "control*"
 Buffer ctrl1, len: 100.62 Mbytes, used: 41.87 Mbytes (41.6%)  23 cycles

========================================================

If I run it with the -a option, it gets stuck:

%bin/cnfsstat -a
Class control  for groups matching "control*"
 Buffer ctrl1, len: 100.62 Mbytes, used: 41.89 Mbytes (41.6%)  23 cycles

Class bin  for groups matching "*bin*"

  Oldest: 1999-08-09  5:08:33,   11 days,  5:41:26 ago
==========================================================

If I try to truss it, I get a loop of:

syscall read(0x4,0x8112000,0x2000)
        errno 27 'File too large'

has anyone seen this, or have any ideas on how it can be fixed?

Thanks...
