My avrd has decided to start doing work.  On an otherwise idle 4
processor machine, it's taking betwene 6 and 14 percent of the CPU.

Trussing it, it's just doing what appears to be name lookups over and
over and over....

open("/etc/hosts", O_RDONLY|O_LARGEFILE)        = 5
fcntl(5, F_DUPFD, 0x00000100)                   Err#22 EINVAL
read(5, " #n #   I n t e r n e t".., 1024)     = 1024
close(5)                                        = 0
open64("/etc/.name_service_door", O_RDONLY)     = 5
fcntl(5, F_SETFD, 0x00000001)                   = 0
door_info(5, 0xFEEC2748)                        Err#9 EBADF
close(5)                                        = 0
open("/etc/hosts", O_RDONLY|O_LARGEFILE)        = 5
fcntl(5, F_DUPFD, 0x00000100)                   Err#22 EINVAL
read(5, " #n #   I n t e r n e t".., 1024)     = 1024
close(5)                                        = 0
so_socket(2, 2, 0, "", 1)                       = 5
bind(5, 0xFFBEE778, 16, 3)                      Err#126 EADDRNOTAVAIL
close(5)                                        = 0
open64("/etc/.name_service_door", O_RDONLY)     = 5
fcntl(5, F_SETFD, 0x00000001)                   = 0
door_info(5, 0xFEEC2748)                        Err#9 EBADF
close(5)                                        = 0
open("/etc/hosts", O_RDONLY|O_LARGEFILE)        = 5

I don't know what it's looking for or why.  I've got VERBOSE in
vm.conf, I've touched /usr/openv/volmgr/AVRD_DEBUG and I've
restarted.  The only messages I can find for avrd are in the system
messages file, and they're pretty normal connects to a library and
the two drives inside the library.

Things *seem* to be functioning, but I'm concerned that it's taking
up so much CPU.  That's not normal.  Anyone seen something like this?

NB 5.1.  Solaris 9.
